Windows Vista 5308 up and running!!!
Finally finished downloading Windows Vista 5308 mage at 3:15 am today. Burnt it on to a DVD, started the setup and now, done with the installation!
a) The installation takes way less time when compared to 5270.
b) The builld is much faster on the same hardware than 5270. The UI is much more refined too.
Will update some screenshots today evening.
