I live in Japan, so I'm kinda stuck in limbo. I have an n810 and can tether it to my softbank 815SH and it works super smoothly... but the data charges are insane. I'm currently in the process of shopping for a different cell provider that will allow data transfers to my n810 without such big charges, but for the most part in Japan it is always assumed you'll browse on your phone itself instead of some other device so they usually don't include data transfers in their fixed rate data plans.

I also picked up an ipod touch for the better music playback and I love the software it has, but the lack of an rss feeder that works offline and the lack of built-in speakers keeps me coming back to my n810 for certain uses. I'm waiting for now till the update coming out next month to see what happens, but if it doesn't allow offline rss reading I'll be jailbreaking my ipod most likely.

If I was really smart I would've gone with emobile because they offer high speed internet connections for a relatively low monthly fee, but I'm not 100% sure they'll work with my n810.
