I know a laptop isn't the best for editing, but I'm not really looking to buy a desktop yet. Would it work hooking the MacBook up to a HD TV? Or could I buy just a monitor & hook it up that way? I have Photoshop Elements.
I also edit with a MBP. I run CS5 and LR3 from it. Mind you I have the maximum 8GB memory and one of the fastest Intel processors. I do get issues if I try to do very much while knitting panos, but with an average pano being over 4GB (the downside of a 40mp medium format camera and using a superb lens like the Pentax FA 645 120 macro that gives SO much detail) that's not really surprising.
I've been using the MBP for photo editing for the last 5 years and haven't seen a problem when exporting it to my desktop which runs a monitor at 2560x1600 resolution. And the MBP doesn't use an IPS screen only the [FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]Cinema Display and the iMacs have IPS screens, I know it sucks why doesn't a $2000 laptop have an IPS but only a TN panel screen but mind you a very good one much better than most other none Apple laptops.[/FONT]
It probably depends on if you are a professional or just learning. I (just learning) only use my uncalibrated macbook to edit and never seem to have issues or comments (related to edits/calibration) on here when I post for c&c.
