Updated to 10.7.1 this morning and has been testing it in a couple of hours.
Honestly, I don't feel anything different with this update. Maybe I don't need it. But alas, it was just a 17.4MB update .. I can't expect something big from it.
I didn't have video freeze problems as on 10.7 like many has mentioned before (I think I got lucky and for that I'm eternally grateful 😛) and still good on 7.1 .. no problem
My GPU temp remains high though, even on idling .. it keeps hanging around 60 - 70C on iStat 🙁
WiFi connection has been stable for me even before update. Again I think I have a quite good machine. The only problem remaining is hot GPU .. and this update still don't fix that .. or it does supposed to be hot than usual, well I don't know 🙁
