Just got a new 13" MBA and will be picking up a 27" iMac over the next couple of weeks. My mid-2007 MBP 2.4 SR workhorse still works fine (multiple battery swaps thru AppleCare and 2 logic board replacements for what I perceived to be suboptimal battery performance). Now, unplugged, it'll give me 2-3 hours of solid Internet, Microsoft Office, Facebook, maybe a little iTunes type stuff (on another note it's in a clear Speck case and has a keyboard protector and I always wondered if that added padding makes it run hotter = crappier battery life). Anyway, with the new computers, was thinking about setting up the MBP in a little nook in our kitchen, plugged in and on/sleep mode all the time, to serve as an Internet appliance, "quick need to get on the computer" device. Will I help it die a slow/quicker death by using it in the above fashion, or are there folks out there whose MBPs have survived and work well being used in this way? Thanks!
