Alyshehata - glad to hear your problems are fixed. How's your battery life?
I haven't seen much improvement. I have a 16GB 2.6GHz MBPr, running only Safari and Finder apps, Dropbox syncing off, no keyboard backlight, and am seeing 6:04 at 91%. Using gfxcard doesn't seem to help a ton here, either.
I guess ~6:30 isn't too bad, but it would be nice to feel like I could use that without having to go into active measures of battery saving...
Practical battery life is closer to 4:30...
