<p>While it's nice to have a decent monitor, I edited my first two years' worth of Monochrom images on a Lenovo portable workstation (you can call it a laptop, if you have a very substantial lap), and the resulting prints look great (I don't post anything on the Web). I take the finished files to a rental facility I use for printing, and when they come up on the Macs they use there, the images didn't need any tweaking to make good prints.<br>
I now do most of my editing on a Lenovo ThinkStation desktop with a NEC Multisync monitor, and I still don't see a huge difference in the images that I originally edited on the portable rig. The MM is a great camera, my primary digicam, and the big prints look like medium-format TMax 400 or Delta 100. Even if I shoot at EI 800 or 1600, I don't need to do much in the way of noise reduction. The RAW files out of the camera are flat, so you have to do some post-processing to give them some zap. But after a while, you can develop some Lightroom pre-sets that do much of the initial work.</p>
