I've turned my gestures off to be honest, I've never been a fan of them, I've got a magic mouse so they could be used there, but I just decide not to use them, they're just not for me.
I do think it is running a lot faster than it's previous counter part (SL), the boot times are increased, loading times do actually seem to be quicker, which I thought was very surprising.
I don't really use Mission control all that much but it is a nifty piece of software to use, if you're multitasking that much that you've got that many windows going on at once.
Launch pad? I hate it, i'm not going to get my applications through there, i'm just going to go through the normal way of getting them through the folder on my desktop, that's just not for me.
Granted, I've only got a Mac Mini, 2.4ghz, 8gbs of ram so my system isn't exactly high spec, but it still runs reasonably well considering.
I'll be getting either a MBP or an iMac towards september, so i cannot wait for that, that will be so much better and the hardware will be much better then (Will on the imac not so much on the mbp).
