one other consideration is that if you intend for your IPP to replace a computer as well (since a mouse and keyboard can be used), then i would go for the larger size. for personal use, i'd say that the ipad can replace a computer completely. i use excel a lot for work and use its advance features and open files that are 10s, even 100s of megabytes in size for work. sadly, the IPP is still lacking in this area. but otherwise, it can replace your computer.
