Hey guys, I've recently made the decision to take the leap of faith and switch to Mac. Not many people I know use Macs so it's kind of hard to get real-life opinions. Basically I'm stuck between an iMac 27 and a MacBook Pro 13. It would be great if anyone could give me some advice as to which one to choose. I'm a fairly casual computer user, one of those typical just e-mail, web surfing, photos, and music kind of person. But while I don't do anything intensive like mix my own records or edit videos, I do have a substantial amount of music, photo, and video files just from everyday life, and I especially enjoy viewing and sharing them with friends and family, which is why I'm loving the huge 27" screen. Right now I'm sharing a big studio apartment with another girlfriend, so I do have the space available for an iMac 27, and I tend to use my computer mostly at home. However, I'm not sure if I'm going to be moving around in the future. The MacBook Pro 13 is really a lovely little package, and I'm sure that spec-wise it's more than enough for my needs, but I have my worries that I'll find the 13" screen to be a bit too small for everyday use. Oh and lastly, do the MacBook Pros suffer a performance hit when compared to the iMacs? I know the hard drive will be a little slower, but otherwise, is it going to be like PCs where the laptops are lagging all the time? Thanks guys!
