RE: android
I was thinking about getting a iPod Touch 4th Gen to see what all the excitement was about. Unexpectedly, I was given one as a gift last Xmas. Not having 3G I soon learned how uncommon public wifis are, slow or fast. I also learned how slow and painful a virtual keyboard on a 4" screen is to use. Dragon helped, but it doesn't cut & paste in to every other app. If you have big hands and/or fingers, or have shakes due to age or other causes, the virtual keyboard is virtually impossible to use.
I can use it as an e-reader under certain conditions, the pro radar weather map is decent, it makes a great internet radio receiver (for 5 to 6 hours, longer if you turn off the wifi and notification services), and my five and 10 year old grandsons think it is a great game machine -- Angry Birds, Sharks, road racing, shuttle landing, etc.
I keep it charged up for them, when they come to visit. My son got a 10" iPad. The virtual keyboard is bigger ... almost acceptable. Other than that it's like my iPod.
