How many Galaxy Tab's were sold in the past quarter?
Apparently enough. Prices for used ones have been going UP on craigslist lately. People are rooting them UMTS (GSM) variants and using them as unlocked phones.
I just bought a 2nd Tab 7 (the original) for my parents. They seriously considered an iPad, but decided that they wanted something that would work well as an e-reader (size) and world phone capabilities for when they travel.
If all they had been doing was web browsing, then I would have suggested an iPad 2.
As an aside, the Galaxy Tab 7.7 (which marks Samsung's 4th or 5th tablet, depending on whether you count the 5-inch galaxy Note as a true tablet) was just released.
The chart is bundling Android tablets together as a whole because they would need to list like 20+ devices otherwise. For pete's sake, even Lenovo has 2 different android tablets!
