Still not sure about the move to Windows 7? Well if my vouching for it on this site is not enough then check out this website called The 7 Wonders of Windows 7.
This site provide several short videos on the main page highlighting new features in Windows 7 such as:
- BranchCache
- DirectAccess
- BitLockerToGo
- Search Federation
- AppLocker
- 3G Wireless Networking
It also has links to the free downloadable trial edition of Windows 7 Enterprise and to Windows 7 E-Learning courses in English, French and Turkish languages. The Windows 7 tutorials alone are well worth a visit and there is even an opportunity to contact them for the DVD ISO downloads to use in a non-networked environment.
There is also a desktop gadget showing the Microsoft SpringBoard Series RSS feed.
P.S. Just ignore the fella in the yellow shirt – he does a lot of gesturing when your not active on the site
