I have developed a nasty case of tendonitis from using my i-pad too much; I tend to hold it in my right hand for extended periods of time when reading and commenting on blogs. Talk about your first-world problem... !
I've been ignoring the subtle symptoms for months, but can ignore them no longer... I'm in real pain! Once I am all healed up, I plan to sit at my desk and use my main computer most of the time. In the meantime, I'm reading your blogs - just not commenting for a little while - you wouldn't believe how long it took me just to do up this small post!
