Help.... I currently have a 2011 13in MBA ultimate with 4GB. I have bible software that will only run in windows, so I have parallel running. These programs have many tabs and windows in them so things get clogged down pretty easy. My page out is ridiculous. I also use chrome on the mountain lion with many windows in my search and study. It is so difficult to bookmark and close on the internet and cannot on the bible programs.And I have several word documents on the window side with different documents open also. I am looking to get rMBP 13 in. to replace my MBA. I want to know should I wait for the Haswell this summer or will the I5 2.5 or i7 2.9 with 256 be good enough. I do not do games and although longer battery life would be nice since parallel does eat up the life to 3 hours or so. I could easily wait til Haswell but does it do me any good? Would I see the improvement? Am I waiting for something I would never really see or need? I will probably keep computer for couple years and sell. Would getting the refresh bring more on resell or does it all get washed out on late 2012 and early 2013 when reselling? I have been on this site for about a month and you guys are smart. I do not know cpu or bottleneck stuff...just tell me should I buy 2.5 or 2.9 or the refresh??? I do want the retina or I would just get the MBA with 8GB.
