WMWiFiRouter is great. As with anything, using the net and wifi at the same time WILL Drain the battery unless you have it plugged, charging AND keeping cool.

Using bluetooth if your laptop has it is better.

Either way the advantage is that if your USB cable is too short to get a good signal, you can use a wireless option easily.

Personally, I have had a huge problem with internet sharing in the touch pro. If I started doing anything intensive it disconnects, so I finally shelled out the $30 for the WMWIFIrouter key and have using that blissfully happy.
