I have an HTC EVO 4G 4" phone and a Samsung Galaxy Tab (original 7" model) and carry them both everywhere. The SGT fits in my trousers pocket, but is just a little too big to be comfortable, and it doesn’t function as a phone at all. Even if it did would be too big to use without an ear wart.
I stopped by an AT&T kiosk over the weekend and played with a Note for a bit, and decided that while there is a little compromise on both ends, this could work for me, and I could go back to carrying a single device, with the added benefit of a stylus.
My carrier is Sprint, and I’ve been waiting for the Galaxy Nexus, but now I think I’ll wait a bit longer to see if they pick this one up.
