So I am at a point where I looking into replacing my 2008 MBP with a new computer. I have decided to go with a desktop since I use my iPad a lot, and recently my MBP has just stayed connected to my 21" monitor. I love my MBP and OSX; no doubt about it. However, when looking at the new iMacs, I am torn when it comes to their price vs. a PC. For example, for $20 less than the 21.5" 2.8Ghz Core i7 iMac, I can get the Dell Studio XPS 9100 and gain 8gb of RAM (total of 12gb), 1TB of hard drive space (total of 2TB), and get a better video card. So do I sacrifice the operating system and go with the more powerful PC? I understand the decision is ultimately personal, but any incites would be great! Thanks!
