KINESISAdvantage2 Ergonomic Keyboard (KB600), Black top case, Cherry MX Brown Switches, QWERTY keycaps

This might sound extreme, but I think this keyboard literally changed my life. I say "think" because I'm not sure what could have been.I am a software engineer. Needless to say, I spend a lot of time at a keyboard. Over the years (I'm 39 by the way) my hands and wrists have progressively got worse. I would hear cracking, and constant aching in my hands and wrists. I just assumed that was par for the course with my job. As time went on, it got worse, and I decided to look into keyboards. I've had the split wrist ergonomic keyboards in the past and I liked them, but I thought I would look into something else.After reading tons of reviews, looking at and seriously considering every crazy keyboard style out there. I looked at all the start ups, oldies, etc.I had some criterion:- Nothing but the best ergonimics- mechanical keys- programmableI finally settled on the Kinesis Advantage 2.Setup was as expected. Now that's because I was already aware that there are KVM switches often have compatibility issues for keyboards like the Kinesis. This prevents you from being able to use the keyboard input on the switch. I have a KVM switch (IOGear Miniview DVI 4 port USB KVMP Switch). When reading the reviews from both companies, I knew it wasn't going to work, but I already had a workaround. Basically, because your keyboard has the multimedia controls (like a lot of other of your cool keyboards) and some other advanced features, KVM switches don't recognize them. That doesn't mean that you will have any drivers on your windows PC (or Mac/Linux/etc) or anything like that. It's just a keyboard to everything else in the world... but your KVM switch. This problem was easily solved by using one of the standard USB connections on the switch. I just have to push the button on the switch now. I also hooked up a standard keyboard for the rest of the people on this planet that don't know how to use my keyboard... so I just use that to actually control the KVM so it's really fine in the end. If you are planning to use a KVM switch have a look at the Kinesis web page, they have identified some that do work, sometimes only in a partial manner.As any other review of the Kinesis will tell you, it takes time to get used to. Plan on that. I spent a lot of time on Type Racer practicing in my down time. I completely stayed away from standard keyboards for about 2 months (mostly). I made a lot of mistakes and made a lot of mistypes, hitting double keys, etc. It was obvious from the start how much better the ergonomics were.I was able to easily program some macros into the keyboard. As I mentioned, I'm a software engineer. There are a lot of patterns that I type many times a day, I can do this with a single keystroke now. So far, I haven't found a need for it yet, but the keyboard has different layer settings so if I'm switching between editors that have different auto completion features (i.e. how {} and () brackets are written out and tabbed... developers know what I'm talking about).The Cherry keys are all they are cracked up to be. It's my first mechanical keyboard set so I don't really have much to compare them to, but the keys are wonderful. They are clicky, but not too bad. People I work with have not mentioned much about it so I assume that it is not too bother some.Now, on to the real reason you would buy this keyboard. The ergonomics...As I mentioned, it was obvious immediately how much more comfortable this keyboard is. I'm not sure exactly at what point it was, but my wrist pain went away... and I'm talking about a 2 months... probably less. I didn't have any diagnosed carpal tunnel or anything like that, but the pain was constant.It's also important to note that I have reduced shoulder and neck pain because my arms are in a more natural position as well.I carried my keyboard back and forth to work gladly every day until I got one for my work. At that price my work wanted a doctors note, which I gladly went for.At this point, I have had the keyboard almost a year. I will now switch between "normal" keyboards and the Kinesis pretty easily enough. It literally becomes painfully obvious how much better the Kinesis is after typing at a "normal" keyboard for more than 5 minutes for me now. My wrists will start to hurt almost immediately and I think that I've been doing this all my life.I'm seriously considering switching to Dvorak now that I have one at work and one at home. I was thinking that it might help me separate my brain more from the "normal" keyboard so switching would be easier. I did get the Dvorak version for work to plan for this and will likely buy the keys for my home keyboard.Have a search on Youtube for a review on the Kinesis Advantage 2. There is a very good one that is about about a 15 minute in depth review of the "Human Keyboard".Pros:- Ergonomics- Program-ability- Ergonomics- Build quality- Ergonomics- Actually smaller than it appears in pictures.- ErgonomicsCons:- KVM Switches... but a lot of other high end keyboards will suffer- It's completely different from all other keyboards (but that's why your buying it right?) so switching between "normal" keyboards can be awkward, but it's not as bad as I expected.- Fatter and taller than a "normal" keyboard but slightly shorter. It might not fit well in those desk drawer keyboard trays.- could be considered loud, but nothing louder than any other mechanical keyboard.In the end, this keyboard does exactly what it says, every other review I read is spot on. If you are serious about your ergonomics, are experiencing pain in wrists and shoulders. I'm not saying this is going to cure you... but it might.In conclusion, I "THINK" this keyboard changed my life, because I will hopefully never know, but I was quite certain that I was developing some long term chronic problem with my wrists and hands. As of a year later, I don't worry about this nearly as much.

So thought I'd come back to give a one month review. I don't feel at this point any new revelations will come thru. So here is the final review.*** Who this is NOT for ***- People that don't type pretty strictly home key (at least for normal typing).- People that 10-key a lot.So this keyboard has keys closer together and a concave shape. 10-key is embedded within the right half of the keyboard. All of this makes it a) difficult to look down and type and see what keys are what, b) creative fingering can be awkward and slow as you lose all the ergonomic benefits of the unique shape of this keyboard.10-key because the alternative function of these keys are painted on the bottom sides facing you of each key. But since each key is down and concave there's limited area to see what each key is. Lastly, I finally learned from Kinesis support that th SPC key becomes the 0 in KeyPd mode. So you can type a zero, it's just a bit weird.*** Who this is for ***If you are pretty significantly a home key typer- you will absolutely fall in LOVE with this keyboard (as I have). the ergonomics are really that unbelievably good. Best I can explain it is, I am not one who has ever had hand or wrist pain when using keyboards. But, using this keyboard just for a short while I suddenly can feel how strained my wrist and fingers are going back to a normal keyboard and even a standard ergonomic keyboard.It's immediately obvious when going back:- why the concave curve- why the "more cramped" keys closer to each other- why these analog keys (the action and feedback is UNBELIEVABLE). I especially love turning on all the tones as it helps me save my fingers from crashing against the bottom and also the CAPS lock indicator.*** The unexpected fallout if you buy this kb ***1. If this keyboard is to your liking, you will absolutely fall in complete love with it. To the tune that you will find excuses to sit at your computer just so you can use this keyboard more. To the tune that you may even feel compelled and tempted to bring it everywhere with you just so you can use it more (like to work).2. I laugh every time I'm at work and I start typing and I start mis-typing characters because my thumbs are now used to being used for del, backspace, etc. and not just the space bar. So when I come up to a task where my thumbs are used on this keyboard, but I'm using another keyboard- my thumbs either hang in the air because it wants to do something it can't, or I end up forgetting and using them anyway and get unintended results. It make me laugh every time now.3. If you switch keyboards regularly (say work vs home) and don't take this with you constantly- even really good typists (e.g. me) will now have to get used to not being such a good typists anywhere anymore. The switching back and forth from muscle memory will become a factor. Even though this is true, I will never go back if I don't have to and may buy extra units of these so I can have a Windows one and a Mac one- then take whatever I need with me.Hope this helps. Good luck.
