Leopard to Snow Leopard was beeyootiful!

Upgrading to Windows 7 was an all-day ordeal.
Someone recommended that i do a system wipe and then install from scratch and I'm glad I did. It took ages but it was a clean install.

Others have been having issues with the upgrade.

Things seem to have sped up on my HP laptop - looks like a lot of the gears that had to churn in the background on Vista have been fixed.

Although, keep in mind that 7 is really just another step towards what Vista was supposed to be. So, really, its a service pack... they are just making you pay for it.
