    So my 19" monitor arrived today, connected everything to my MacBook and am running in mirror mode with the MacBook closed. Quick question, is this bad for the MacBook if th heat can't escape properly?

    I beleive it is alright. If I understand ciorrectly the old ibooks didn;t work in this "clamshell" mode beacuse they "vented" through the keyboard, unlike the powerbooks (and I assume MBs and MBPs) which vent out the bottom/back.
    I run my 12" PB that way all the time connected to a 20" monitor, I just have it positioned such that there is good airflow all around it.

    The MB and the MBP were designed so that you can work in clamshell mode on them. That is the main reason for those huge vents in the back. The problem with the iBooks and Powerbooks before them was that they discipated heat from the keyboard, and, when closed, could damage your LCD. If I were woozlewoozle, I'd be careful running in clamshell, but you should be OK.
