I'm still using a first generation Motorola Droid, personally. Were I to switch up, though, I'd probably go for one of the samsung galaxy S serieses. I've played with them some and like most of what I see. But I'd have to root it, of course. They try and flimflam you with their carrier-fellating "wireless hotspot" apps that only work if you buy their priciest data package, but I'll take a good ol' fashioned tether for nothin', thanks.
