I seriously have a problem.
1. I ordered the rMBP right after it was announced, because I waited years for an all new design. (coming from a non-unibody MBP early 2008)
2. I'm working on my Master-Thesis in architecture right now. I've got 2 months left and really depend on a competitive Laptop.
3. My MBP (early 2008) did not turn on anymore just last week. Logic board is defect.
4. OK. No problem, because tomorrow the new rMBP arrives and I got to use the white MacBook of my girlfriend the past week. Already enough time wasted on getting out the hard drive and installing all those heavy applications.
5. Not even knowing about the UI-lag issue, I noticed the sluggish behavior from the first touch of the trackpad on a rMBP in store. I instantly knew that this is NOT NORMAL, that this can NOT BE A FAULT FROM THIS PARTICULAR MACHINE and that this performance would NOT PLEASE ME, IN FACT WOULD SERIOUSLY SLOW DOWN MY WORKFLOW IN EVERYDAY USE!!!!!
6. I've been reading every single post in this forum about the lags in the UI and scrolling and was really relieved, when I heard of ML will fix all the UI performance problems. I really was looking forward to this amazing machine again.
7. But with time, posts were getting more pessimistic. The Anantech review talked about, the hardware is not ready for this high resolution. And people were complaining about even under ML not everything would run as nice and smooth as on the older generation MacBook Pro. One member said, even Photoshop CS6 would not run fluid on the rMBP (rearranging layers) and I really depend on a fast working Photoshop!
8. I really don't know what to do now. I can not test the rMBP under ML. ML will come out in a month from now. I can not test ML on rMBP in the first 2 weeks and possibly send it back.
9. I can not return the rMBP and buy either a MBP (2012) or a MBA (2012), because first, they would again take 2 weeks to get to me (ordered over Mac at Campus = great discount) and second, the MBP would sure please me for the work I have to do but would not please me as THE NEW TOY at all, and the MBA would be THE NEW TOY but I'm afraid it might not handle all the stuff I need to work with (CAD-drawings, large Photoshop files with over 1 GB per file, Cinema 4D renderings).
10. I hardly have time to busy myself with reading and reading and posting and posting in this forum.
11. I do not want to waste any more time to think about weather or not the lag problem will be gone or "enough" gone with ML.
12. I dont have time to run tests with some ML DeveloperPreview, never done it.
13. I just need a working Laptop and I do not want to buy something that expensive if it would not work. Remember I come from a MBP early 2008 and waited really long for an all new design MBP and saved money for it.
14. I just do not know what to do any more......
