I plan on using either the Apple LED display or another one display as some kind of 'hub' for the MBP when I am at home. I require a fairly large workspace and for that reason was considering the 15" MBP. The downside is that it does reduce portability fairly substantially, and I am under the impression that the 13" MBP now has the performance to match my needs. Would running a MBP in clamshell driving a large display for extended periods of time result in heat problems, especially screen distortion (as this is probably what I would do when at home)? I sincerely hope not as it would be quite an ideal solution. I don't really fancy the clutter of having the laptop open on the desk, I would rather hook it up to the monitor and power and use a bluetooth keyboard and mouse, effectively landing me with both a desktop and notebook in one integrated system. Thoughts?
