You have to check the specs carefully. Some wireless connections have slower download speeds than cable and the cheap ones have uploads through the telephone line like dial-up.
Precipitation and heavy clouds also affect wireless if the dish isn't big enough.
On the upside your plan is unlimited- many cable companies are instituting dl and ul limits with extra costs if you exceed them. Also wireless can be cheaper.
All told it depends on your needs...or in Ramona's case maybe the answer will come to him in a dream.
