I've been wondering that for years. Many netbooks and ultra-portable laptops have this at least as an option these days. I'm going to have to get one of those battery powered 3G->Wifi routers, my USB modem sticking out the side scares me (people walking past it are a liability). Annoying - another device to drag around - but I guess it'll probably come in handy in other ways.
