I'd been reading about these taxes, and I agree with you, just what we need is another tax.

I'm sure this debate will be ongoing for quite awhile.
The only good thing I could see coming from a tax on cell phone use is that maybe people would be forced to curtail their use when driving, which may prevent some accidents.
Did you see the report on television with the train engineer that was texting and caused a huge train wreck? The use of cell phones while driving has caused many an accident and I believe should be outlawed. At least they should be totally hands-free while being used while driving. Of course this is just my opinion, but I can't even count the times that I've been narrowly missed by another car with a driver having a cell phone to their ear. It's scary out there.
