OK, this is PURELY for thought. I'm not ready to purchase yet, and I realize things may change between now and when I am ready, but let's assume things stay the same for the sake of consideration. I currently have an older white iMac and a quite old PowerBook G4. My wife has a year-old Macbook, but that's solely her machine. I'm looking to replace my machine(s). I fell in love with the 27" iMac when I first saw it. However, if I get a 27", I'll have to limit myself (more than likely) to the base model at $1599 (with edu. pricing). I have on hand (from upgrading my sister's Macbook) 2 extra GBs of DDR3, so I'd be able to upgrade it right away to 6GB. If I buy the 27", I'll definitely have to sell my iMac and probably my PowerBook, too, in order to get the funds to purchase it. I don't need a laptop very often at all, but I LOVE having one. So option one is the base 27" 3.06GHz C2D, upgraded to 6GB of RAM. Option 2, then, is a 13" MBP ($999 for the 2.26GHz refurb) and a 24" ACD ($599 refurb). Add to that the fact I'd need the memory upgrade ($72 for 4GB) and a hard drive upgrade ($90 for 500GB), and you come up to a total of $1760. That's a bit more than the iMac, but its portable, and I can buy it a piece at a time. Not to mention I wouldn't HAVE to get the ACD; I could get a cheaper 24" LCD for <$300. What do you guys think? I know the iMac would be more powerful and the 27" screen would be awesome... but I really like having a laptop (even though mine is ancient). Or should I consider something else altogether?
