I read an article about just using a laptop as your main computer, desktop. So I went to a MBP 2.16 dual core version which has been working out except for times when I need to get accurate color correction for my pro photography business. I have an older, too old now CRT that I hoop up to it many times for photo editing but now I realize that that monitor needs to be replaced. So here is the question what are the pros and cons for adding another computer, do I really need it. I am trying to make a decision. I really like my MBP, I can do everything on it and the speed is fine. Also having only one computer is easy for backing up and not worrying about file sharing and all the nonsense I guess. I have an office with my CRT in there much most of the time but it's dark and boring so I bring my laptop in the kitchen where I surf, edit and watch tv from the living room.. That being said I just started to get the bug about a new quad Imac 27" and went yesterday to look at it. I came very close to walking out with it. Yes it would be awesome to have but do I really need it? The other alternative is buying the new 24" ips screen and running that off my MBP when I need to do critical photo editing. Then I am thinking my laptop is over 3 years old now and wonder what is the life on it? I would hate to buy the nice desk top and not use it, plus I would need more backup systems etc. I do you external HD.s for all my clients photos so if I choose to work on them I just move the HD. Any advice?? New 27" Imac or will the 24" monitor suffice?
