This is why I keep coming back and reading this thread. So far (I haven't done tons of research) the Tab has the best features of any tablet I've seen.

1) 7" screen (this is really the size I want)
2) 1024x600 resolution, most other 7" tablets seem to be 800x480
3) GPS, seems like wifi tablets exclude the GPS (built into the 3G chip?)
4) Reasonable CPU/mem/storage, most of the other tablets are using older CPU's, less memory, less storage
5) Other tablets that don't have a gimmicky connector, either don't have video out, or are limited to SD video.

Admittedly most of the other Tablets are considerably cheaper, but due to the older CPUs being used, are going to be much less capable. Access to market on other tablets is questionable (varies).

IMHO, the Tab is currently the reigning champ in the tablet division, standing well above the other tablets I've seen. However, I do think the pricing is off on the high side. I'd bet that at $400, Samsung would still make a nice little profit, and wouldn't be able to keep them on the shelf.

Personally, I'd like a 7" tablet @ 1280x720 (or even better a "retina" display @ 1920x1080) with GPS, wifi only. If I have to take 3G to get GPS, I would. Either not get a sim, or get a pay as you go sim.

In the meantime, I'll keep looking, and keep reading here.
