I know that Scott Grumby did some software that turned T300 into a wireless modem and a lot of talk about in a windows machine ot use serial cable.

I see there is a PDANet for Treo 600 that uses a UBS cable.

Are these the same software programs?

What are pro and cons if using a windows based machine like my IMB T21.

Thanks. I realize these things have been discussed, but I could not find this contrast anywhere. Just need to know which one to by. I am on sprint plan.
