I'm in a hotel room using free wi-fi. Yes, I know that's unusual as you don't often get free wi-fi in hotels... but I'm noot using the hotel's supplied access point.
Let me explain...
I've got my Eee... which is wi-fi enabled.
I've got my phone... which is 3G enabled, but also has wi-fi capability.
So, I've turned my phone into a wi-fi access point, using it's own data connection (gotta love T-Mobile's data plans), and I've got my Eee connected to that access point.
Yeah, it's not particularly fast, but it's a good, solid 3G signal so very usable.
