I've seen a few people asking what's the best prepaid phone to get and other post that recommend hobbyist get a dedicated hobby phone, if they want to keep things on the down low.  Has anyone ever used magic jack?

I just bought it due to my constant travels overseas.  A co-worker of mine has it and it's simple to use.  You can get a local number and as long as your computer is on, you can make/receive calls.  If a hobbyist has a dedicated laptop or other computer this could be an option.  Only cost $40 for the initial purchase and then $20 a year after that.

Just curious to see if anyone else has used this...
