Yes, at some point. I think I might wait until August or September tho' to see if other manufacturers jump in*. Assuming my ability to control my techno-lust lasts that long!
Probably will pay the extra for the Sam 5 with 3G as I appreciate good build quality and the additional connectivity option.
*ideally I'd wait for an ARM version with super battery life, but who knows how long that will be if ever.
