I had been looking to take screenshots on my android for some time now. But couldn't find a way out without rooting the phone. So it was great to find another way, although a round about one. It suited me because I already had the java and android sdk in place on my work laptop. Yes, its a work around. And you can read about it here. Have also read that the next version of android, i.e 2.2 froyo, is supposed to have built in support with key combination press. Don't know how much of it is true.
