I want to get the SR MBP as my "everything" machine (replacing my iMac) and an external monitor. The 23" looks very appealing, but as with anything Apple, pricey. Does the 15" MBP and a 23" Cinema HD display make a good combination/investment? Is it usable in a dual screen mode (e.g., what kind of resolutions does each monitor get), as I know that you can't use the external monitor's full potential if you have it in dual screen. Other than that, I've decided on a 160 5400RPM. I have a lot of "STUFF" on my current iMac, using around 205 GB. I think I could probably shrink down to 160 and put some stuff on an external drive. I just want to be able to carry all of my important stuff with me. I'd love to get the 200GB drive, but 4200 RPM just seems too slow for an "everything" machine. I do a *small* amount of video editing and a smaller amount of 3D rendering with Blender, but it's home video type and hobby stuff that I'll likely be doing on an external drive anyway. Other than that, it's all general use and web development. The 5400 should be fine, right?
