Managed to 100% switch to my new tablet PC and it's awesome. It's a Lenovo X61 Tablet, 64bit, 128 VGA and 4 GB RAM.

Vista rating goes up to 3.5 and everything runs very smoothly. So to put it to the ultimate test i just opened up my virtual PC and opened up 2 instances of Windows XP Pro, 1 Instance of Windows Vista and 1 instance of Windows Server 2003 at the same time. Tried opening several applications inside these virtual machines including, SQL Server, Visual Studio 2008, Expression Blend, Express Web etc,. Still it had power to pump in. All 4 Virtual Machines ran without any problem.

Woo! Hoo! ... finally a machine without worries.
