Yeah. I do know that this is still reality for some. But it doesn't have to be. And in some years, lets say... 5-10 years almost nobody will use thumb drives or SD cards etc. anymore.
Wireless is indeed the future. You can live with it or not. It's up to you.
srracer's point is that often the "not" is forced upon you and availability 5-10 years away is irrelevant today. It is not up to you. I just went on a week-long trip to a place where no wireless is available, in January there will be another week-long trip to another location where it is not available, and next May I'll be in yet another location for 3 weeks where wireless in not available. For that matter, in all of these cases a wired Internet connection is not available (though electricity is). I don't care about 10 years from now, I need to work today's (and next year's) problem.
