While I'm pretty new to the game (only been a user for about 4 years), I still love my Kinesis. Prior to getting a Kinesis, I was buying a fresh MS Ergo 4000 once every 6-8 months because the etchings in the keys would wear off, the membranes would get gunky, certain keys would get sticky or soft-to-the-press, etc. The Kinesis has permanently resolved that class of issues for me (and more than paid for itself just in the cost of replacement keyboards, not to mention heretofore staving off the need for carpal tunnel treatment). I convinced a friend to get a Kinesis last year. I did a thorough cleaning of mine around the same time and was pleased to see that after a little elbow grease, the brand new unit and my aged unit were practically indistinguishable. Kinesis keyboards are tough and one of the few buy-it-for-life-priced devices that actually seems like it'll never wear out.
