I do like the sound of: Galaxy Tab M = 7" Galaxy Tab L = 8.9" Galaxy Tab XL = 10.1" with of course the Galaxy S / S2 as the phone size. Perhaps even drop the Tab from the name.
I still hope to see a "syncronizer" app that would work using push technology, a list of information/files/settings to sync and a widget. Tap the widget and presto, information goes flying through the ether from my phone to my tablet for a seamless user experience. Tap it on the tablet, and info goes back to the phone. Web pages, where you left off in your book, game scores/levels, etc. Set up as much or as little as you'd like synced. Contacts and email are already synced, why not other information as well.
