Roy,
If that is your only reason for wanting to do it.... It really depends on how much work you want to put into it.
If you dont care about making something hi def and don't have a smart phone, I would suggest a possible alternative - an iPod touch. Easy video taking, cheap decent editing software and upload without messing with conversions.
BUT, you will have limits like lack of zoom, etc. It really comes down to how much work to put into it and budget.
