Two things to be gleaned here. 1) Samsung's new Galaxy Tab 7 Plus is almost exactly like the 10.1, 8.9 and 7.7 tabs. 2) If you bought a first generation Galaxy Tab 7 and hoped for Honeycomb, you're probably screwed.
Basically, here are the differences between this and the Galaxy 10.1 or the Galaxy 8.9. It's smaller, at just seven inches. It's a little faster, with a 1.2GHz dual-core processor vs. the 1GHz on the other two. And it has an HSPA+ radio, which should make downloads nice n' speedy (though that makes it negligibly thicker). It also sports Samsung's bright and cheery TouchWiz UI over Android 3.2. It's basically a faster version of the original Galaxy Tab 7. The bad news is that means that if you bough the original Galaxy Tab 7, which launched with Froyo, and you've been hoping for a Honeycomb update, this thing probably just took a pee a your dreams.
No word on pricing yet, but given that the screen isn't quite as fancy as the Galaxy tab 7.7, it'll probably be cheaper. Seriously though, Samsung, what's up with all these look-alike tablets? Where's the creativity? I fell asleep twice while trying to write this three paragraph post. It will likely be available by the end of October.
