Hi I won this with work but .... Can I increase the memory ? It won't let me download adobe and so cannot read some files , also is there a free word app ?
You can only download apps from the App Store, or Cydia if you jailbreak. However the iPad will read most formats, including PDF files, natively. You'll still want a good app to read the files. Many users find GoodReader the best all around app for viewing PDF. It's also the closest thing to a file manager you'll find on the iPad. Each app has it's own file space, so moving files (copying actually) takes a bit of getting used to.
There are several Office compatible apps. None of them offer the full set of Office features. Here are a couple reviews of the more popular apps.
