If you can get proper broadband, go for that instead. I can't yet, so I'm running it on my lap top. Big improvement in speed for bulletin board and text type browsing. Graphics tend to suffer, and at the maximum setting are almost unrecognisable.
Yesterday in a hotel with a 26k connection, I really noticed the difference with it on, as at this speed without it internet usage is painfull.
A good stop gap for the moment, but roll on cheap widespread broadband.
