Before 2 weeks ago, I would have said yes. Now, after using an android phone, I am not sure. I love being on a mobile OS and having some resemblence of a file system. Ie: I can attch photos to MR from my phone without using a 3rd party photo hosting service.
Yeah, seems for some of us the choice is not necessarily old iPad vs. new iPad but more iOS vs. a more open system.
I expect the new iPad to come out in 4-6 month. By then we will have a better idea what the iOS develops into and what competitor tables are out there.
