I'll be honest, I played with the developer's pre-releases a bit over the last few months, but I didn't really switch to it until today with the official release. (I actually haven't really switched, I installed it in a separate partition, but it's a step up from running it in a virtual machine.)

I am going to really give it a good exclusive 1-2 weeks before I decide for sure, but I think I'm going to be a switcher. At the moment it's noticeably snappier than the snow leopard I was running but part of it may be the windows effect that it's just a fresh install.

So, what are your first impressions? Too iPad-y or not really?
