I want to get the rumored new MBP right away, and it will be my first Apple computer since the Macintosh Classic. But there's a lot of new stuff supposedly in this system. Ivy Bridge, retina display, nVidia graphics, more powerful battery. I also remember hearing there was a problem with some early batches of the last MBPs that used nVidia. So I'm curious whether you think Apple's releases are pretty solid or whether there is some wisdom in holding back and waiting a few months before purchasing a system? Thanks!
