I'm planning on getting this bag: http://www.timbuk2.com/tb2/retail/ca...?categoryId=21
It's lined with corderoy...how cool is that?
Right now, the industry standard for WiFi is 802.11g (used to be 802.11a, then b, then g). Then, a lot of routers started pushing "MIMO" (routers using more than one antannea, and other techy goodness).
The current "future" wifi is the 802.11n, which looks to be the new industry standard.
It transmits further and a lot faster.... but if you are just using your wireless access to do stuff online (As opposed to working with other computers on a network), you're fne with the normal wireless card that comes with the 1210. The "n" technology looks sweet, but it really comes down to how fast your internet connection it, because being able to connect to your router at 200-500Mbit/s is overkill if your internet is only feeding you 10-100Mbit/s.
So, to make a long explaination short (too late), the draft N will give you a bit more range than the normal card...but if you are using your laptop at school or at home with your own router, you don't really need the extra range
