Hi guys and gals, I'm looking for some of that Mac Rumors wisdom! Apple agreed to replace my 2009 MBP with a 2011 version because of ongoing display flickering and graphic issues. I am extremely impressed with this and very happy with Apple. So my new MBP turns up on Wednesday, it's one of the new models with Lion preinstalled and the new keyboard layout. Even better! Now I boot up and try to restore with my time machine backup, which hung and refused to install, this is hard reboot number one. This time I try to set up a normal account, it gets to the screen which asks me to choose/take an account picture, except the camera screen has a line through it with the text Camera off on it. This gets me worried, so I try to choose a preinstalled icon and it freezes again, cue hard reboot number 2. This times it refuses to boot past the Grey apple screen - reboot number 4. I boot into Lion's recovery partition, tried verifying the disk, repairing permission etc but nothing would get me past the boot screen. I had to format the preinstall of Lion and wait 5 hours for Lion to redownload (but that's another complaint...) Thursday morning and I finally have a working machine, except finder is laggy, apps take forever to launch (including safari, mail and system preferences), to the point where finder needed relaunching but the system hung and - yup - another hard reboot was needed. It's seems to be working ok now, albeit a tad sluggish and apps sometimes crash instantly when launched. I'm not sure if this is down to Lion or if it's the machine. Do you think I have a solid case for another replacement? I just don't want a repeat of last time with problem after problem with my Mac, and this has hardly gotten off to a great start! Or am I just being picky and it's just caused by the instability of Lion? Help me Mac Rumors!
