My MBP with external monitor fits all my computing needs. My boat anchor XP Desktop system is on its last legs. It has served as a hub connected to a router which networks a WiFi printer, Slingbox, a MBP, a Macbook, an XP laptop, and a wireless web cam. The non-computer devices have required a computer hardwire connected to the router to configure those devices, IIRC. I'm thinking about an iMac to replace it. The other option would be to have my MBP replace it. My question is, I don't want the MBP tied down all the time, e.g. for upload/download tasks having it hardwire connected to the router would be great but of course I'd like to disconnect the laptop and take it around the house, outside, etc. when I want as well without disrupting the network otherwise. Can the MBP simply just be "unplugged" and go wireless or be plugged back into the router when I want without causing major issues/headaches, or would it be best to have a dedicated system to be the "hub" computer of the network. Thanks.
