I have the same feeling about a tablets in general, I want one, but can't find one that:
A) Suits me and my needs/wants/desires (oddly enough the iPad matches most of what I'm looking for)
B) Will I really use it ? I have laptops, a desktop and a cool phone that does cool things
C) I don't really like the current Android 3.0 tablets, Android 2.X tablets do everything my phone does...
D) Do I wait for Windows 8?
If I were you I'd wait 3-4 months for the iPad 2S/3
