These days I use my Transformer Prime more than I do my Dell laptop. I probably use my laptop once or twice week and that is primarily to create content (word processing documents that require a bit of image manipulation, presentation file creation etc) but 7 days a week I use the Prime.
I got away with using the Prime. I wasn’t super confident as Android 4.0 whilst being reasonably stable and visually pleasing, was a little unstable. I would get an app crash once every 2 days or so and perhaps twice a week I would have to reboot the device.
That all changed when Asus upgraded the Prime to 4.1 (Jelly Bean). If you have been holding off getting an Android tablet, I think that if you can get one running version 4.1, now is the time to take the plunge. Solid, reliable and very productive.
