I'm not ready to replace my laptop with a tablet- I use the laptop for heavy photo editing, 3D modeling, some database/spreadsheet stuff and document creation. However, I'm increasingly thinking a tablet would be better when I need to show 30 or 60 photos/images to someone. Tablets are faster and easier, and some have beautiful displays. So, I can't yet justify the $400 to $500 stuff, but I could spend up to $200. I'm seeing generic 7" Android tablets for $79, and Galaxy Tab 2's for $179. Any thoughts on those, is 7" sufficient for good photo viewing if I'm just sitting at a table with one person? Is there a lot of quality/image/speed difference between generic and Samsung? Or should I just wait 6 months until new stuff is out?
