I'm considering a 7' GTab (may look at the 10' as well) but have a concern. I'm visually impaired, so I need to know if display size & font sizes are adjustable. I know about pinch & zoom, but is that available in all applications?

I thought I was going to love the BlackBerry PlayBook, but in the email and Facebook apps, the fonts were simply too small.

Appreciate any input, thanks!
