Let me preface this by saying I'm not looking at buying for another month as I'm waiting to see what comes out from Apple at the end of the month but I've been trying to figure out which combo works for me. I currently have a Rev A 15 in MBP which is almost 4 years old. I've maxed out on RAM and replaced it with a 300 GB hard drive but it's getting really slow. I do a lot of photos when I travel and I travel everywhere (work and pleasure) with my Mac. I just started a new job and will be traveling a lot but will also have my work PC with me. So I've thought about the following options: 1. Replacing my 15 in MBP with another 15 in MBP when the new one comes out; 2. Buying a 13 in MBP which will be easier to travel with and buying a 24 in monitor so I can plug it in at home and work on photos; 3. Buying a 27 in iMac and use it as my main computer while taking my old MBP on the road with me so I wouldn't worry about banging up a new MBP. When I'm on the road, I don't do heavy duty "work" on photos, etc. Does anyone out there use their computer the same way I do and can give me suggestions as to which option has worked for them? I originally thought about getting two new computers but (1) not sure I want to spend so much and (2) want to avoid syncing back and forth. Any advice is much appreciated.
