How to avoid sore wrists
JayM: I'm working through some wrist/hand issues now, and I've found that the biggest key in prevention/healing is taking breaks.Find some free software that will time your computer usage (I use Time Out for Mac) and force you take 10-minute breaks every 30-45 minutes or so.  I also take 15-second breaks every 10 minutes, which may sound pointless, but more than anything it's just a safety net to keep me from tensing up for too long a period of time.As for external keyboards, if you can afford it, I suggest investing in a Kinesis Advantage (~$300).
