My laptop is dying and the one application I need to run is killing it: Aperture 3. I can't afford the 17" which is what I really want so I'm thinking either the base iMac or base 13"MBP. The iMac is half the price of the 17" and faster but is weighed down and of course not suitable for travelling. I go from Germany and the UK often. The 13" MBP is very good but its 2.4GHz processor over my 3 year old Core 2 Duo 2Ghz processor doesn't really seem much of a stretch with regard to crunching 20MB raw files. I'm stuck at what to get. I probably won't sell the existing laptop because its been modified far too much and won't sell very well so I intend to keep it if I get the iMac and least I can travel with a mac still. If I get the 13" MBP then I would have to sell it for whatever it gets, if only to take off some of the punch of buying a new Mac in the first place. Thoughts? Also prices are at HE price. So it is £850 as the absolute limit for upgrading. Just thinking about it actually, I could save more money by buying the Mac Mini as I have a spare Keyboard, Mouse and Monitor about but again, processor wise, I'm not going to get a good return on my investment. Side note, what is happening with their processors! Its been 3 years ago since I bought my last Mac and the clock frequency has hardly moved.
