Hi guys, I was considering to replace my iMac with a MBP because I am gonna need the mobility a laptop offers in a year or so. Anyway, the majority of the time, I think I'm gonna use it as a desktop replacement with an external monitor. I still don't know if in clamshell mode or both opened, but I am more inclined to think clamshell mode (with the notebook closed) will be good for me. Anyway, the point is: Using a notebook in that way, what should I be worried about? My current iMac is on like always, it goes in standby when it needs, but apart from that, I only shut it down for 1 night every 10 days or so, and it's going good with this rhythm from 4 years. Will the MBP get damaged being used like this? Does it support to handle this load? Of course, when I say I keep it open a lot, I don't mean doing heavy video editing stuff, the majority of the time is idle or downloading something. What about the battery? Using it as a desktop, I'm sure I'll waste a lot of cycles, in no time, but I have no problem in changing the battery after 2 years of use for 200 bucks, so that I can get a happy 4 year life without any problem. What are your thought on this? Did your battery get drained a lot after a lot of usage? Is there anybody else that use the MBP as their only computer?
