I was lucky enough to have been gifted an iPad just recently. For one thing, it was good timing, as my impulsive nature would have led me to go out to buy an iPad 2 when it launches next week. For the main purpose of just trying out specific iPad apps what I have is more than enough (I have the 16GB WiFi version). I'm still more inclined to take my Galaxy Tab with me to work as it's the much more portable option - but it'll be interesting to see if that will change.
I'm looking forward to trying out some of the iOS/iPad only applications such as Chalk from 37 Signals and Reeder.
