I am thinking of getting a MacBook Pro (possibly a MacBook - after Santa Rosa) along with a 23" ACD as a desktop solution rather than a Mac Pro or a 24" iMac. I guess the Mac Pro may be near the same cost for much better power, but I don't know that I need it, and the current Mini is not an option. My question is. Can the MacBook Pro/MacBook run off the power cord with the battery removed? If it is going to stay plugged in for days or weeks at time I don't want to kill the battery by leaving it in there, nor do I want the heat that comes off the battery on my desk all the time. I know that it's not the only part of the notebook that gets hot. Also, I would most likely use the 23" as my display with a BT KB & MM and close the lid, unless I'm working on video and want a separate playback screen. I'm not opposed to dual screens if it is a pair of 20" or 23" side by side, but I dont like using two screens when one is an elevated monitor and the other is the portable on a desk, not to mention the size difference. Would there be any danger to standing the notebook on its side while in use, like an external drive to save desk space. I guess my other option would be to slide it onto the foot of the ACD and put the keyboard in front of it. Thanks. BTW, if you think this isn't my best solution, feel free to give me suggestions of setups, configs, etc.
