Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
Your comments: I beg to differ, "-_-" (comment #2). Here in the Philippines, when PDAs were new, lots of people got away with cheating. They'd pretend to use the PDA as a calculator, switching to their notes when the time was right. :-)
Even today, when we have on of the highest cellphone usage rates in the world (http://www.newsflash.org/2003/05/tl/tl012150.htm), this trick is still possible. Our older teachers simply don't realize the capabilities of today's gadgets.
So I guess the technology generation gap
applies here too.
