I'll keep Vista as long as I can, as I have the disk space and like having the option of (short of a kernel corruption) of dual OS's for redundancy while on the road, in addition to multiple ISOs to re-install in worst case scenarios.

My W500 is a Core 2 Duo 2.53 GHz and I've previously upgraded the DDR3 RAM to 8GB and, along with the 7200 RPM Seagate Momentus drives, this is already a pretty snappy machine.

The thing I was curious about and noticed is that with all the backing up and restoring that went on with the upgrade, along with its length, is if the Windows.old thing is still going on in some manner during the upgrade. Reason I ask is I noticed after upgrade the partition was heavily fragmented. I use IOBit's SmartDefrag and like it a lot. Ran a deep optimize and then Wise registry cleaner and this thing is very peppy.

I'll do that though with Vista when the time does come and maybe snapshot the registries before and after and poke around a little.

When you get ready to dump the Vista, it would be interesting to see how an in-place Win7 Upgrade done on Vista compares to the one you did on RC.

I ran RTM upgrade from RC side by side with clean installed RTM for a month and the clean install was snappier by comparison.

The 7 RTM was a great improvement over RC, much snappier without the monitoring software. I wouldn't settle for any less than that, and certainly no hangs ever!
