Think Jim may have mentioned this a while back but have been hearing rave reviews from pc novices to hardened Techies.
Plenty of info in the link and via Microsoft but in a nutshell its a free way of accessing a PC and helping someone remotely, as a VPN, for file transfer plus simply showing photos and presentations . Ie ideal for LDRs and helping the family back home who may not have a computer whizz at home anymore...
Its number 9 in Cnets chart which means a lot of people are downloading and using always a good sign and the reviews are excellent..
