I upgraded my 32GB wifi iPad to a 64GB 3G iPad2 the other day and I like the lighter weight and slimmer size etc. Both the Touchpad and iPad are better than any other Android tablet simply because the 4:3 screen is more suited to the magazine/book layout, and by book I mean non-fiction as opposed to fiction formats. The Android widescreens are fine for ebooks and more than likely comics look fine on them as well but 4:3 is better suited overall. My mate has a Xoom and I am not impressed with the page display on that thing at all.
If I need a 12" display I'll pull my Toshiba Portege Tablet laptop out of the cupboard.
