A great question. There's obviously pros and cons to each of those sizes, and your options are certainly constricted down at the 7-inch end. That said, the now-discounted Galaxy Tab and the still-growing BlackBerry PlayBook would fit the 7-inch bill, and the choices spread out significantly when creeping up to 10-inches. So, what say you?
"I'm in the market for a tablet, mostly for content consumption but also for checking emails and being somewhat productive when I feel like it. I've never owned one before, so I'm wondering what size is best. I could get a 7-inch, 8.9-inch or 10-inch tablet -- I'm more concerned with the size than the OS, frankly. I need it to be portable, yet still feel "bigger" than my Droid X. Any opinions from those that have used multiple sizes? Thanks!"
