I picked up the 1st gen 16GB wifi on launch day and about 2 months later, sold it on eBay (for a profit) & picked up the 3G 16GB, my wife has that one now. I picked up the 16GB wifi black iPad 2 last week just in time for my trip to Florida. PDAnet saved me $130 so I didn't need the 3G this time.
I'm still happy with my iPad(1) 32GB wi-fi (Picked it up a few days after launch). The only thing I'm missing is cameras, but I know I wouldn't take photos/videos with an iPad anyway. I have an iPhone for all of that.
I've had an iPad 2 White, 32 GB, 3G w/ AT&T for almost a week now! Absolutely LOVE taking notes in class with it. (My Psychology professor was trying to take it hahahaha)
Very impressed so far, but still only have a minimum of apps.
