As you see, I'm quite a bit faster now then I was before. Not to mention the added benefit of reduced risk of RSI. It's been an interesting experience to completely rebuild muscle-memory. For the first month or so, I was not very productive, but it was during a not-so-busy period ;) In my opinion, it's a good investment for anyone who types a lot as part of their profession.
