I have a new base 13 MBP and I'm a little confused about whether it's actually running 4 threads or two. iStat Menus is displaying 4 processor threads, and the Apple MBP description on their site states that hyperthreading is now standard on all MBP's. However, while iStat shows 4 threads, it's really 2 identical threads x 2, and I have read that all Core i5's have hyperthreading disabled. Does anyone know whether it actually is hyperthreading or not? (and I know this means nothing in real world applications, especially for the minimally intensive stuff I do, I'm just curious). Thanks! PS Has anyone else noticed that MacBook Pros handle like well built tanks compared to the flimsy MacBook Airs? I sold my 2009 MBP for a new MBA and simply could not get into it. MBP has better build quality, better screen, better keyboard.... hell pretty much better everything except for weight.
