My 7" tablet (Huawei S7) runs android 2.1 and can do everything you asked about. About the only thing it's missing is flash 10. Hasn't been a big deal. It's basically a giant sized N800, only better.

It should get an upgrade to 2.2 in the very near future (officially) and progress is being made on 2.3. I think the majority of android devices have gotten updates (whether official or not).

On the other hand, I'll make you a deal on a used N800. I haven't used it since I got my N900 for Xmas 2009. I don't use the N900 much anymore (except as a phone) since I got my tablet.
