I know this is really out of consideration, but I'm loving the 15" early '08 I paid $90 for on the Marketplace here.
It has the "standard" 15" resolution of 1440x900, and the 8600M is no slouch(even though there are much better GPUs on the market now. The screen is LED backlit and is matte-IMO, the best combination short of the hi-res matte screen on the 15" Unibodies. Supposedly, the '08s have GPU issues also, although I'm crossing my fingers that I can get a few years of use out of it.
It's maxed at 6gb of RAM, and I put a 500gb hybrid drive in it. It's a 2.4ghz C2D, and is no slouch under Mavericks. I've been using it most of the day today(after cloning my 13" 2011 onto it), and it has actually perked up a bit through the day. I'm told this is normal with hybrid drives, as they take a little bit of time to learn your habits and what it should cache in the SSD portion of the drive.
Unfortunately, I'm stuck using(crummy) Office 2008, as I'm pretty sure my 2011 license is only good for one computer. The IT store at school won't sell me another copy(I haven't tried on Office 2011 specifically, but have bought enough other software to know that it's a one time deal), and I really don't want to pay $80 for it retail. I guess I've been spoiled by $10 Microsoft software
(and sometimes even free if it's older software and the guy who I always deal with doesn't feel like ringing it up-the last time I was over there he put the 2008 ISO on a flash drive for me). I'll read the EULA on my Office 2011 disks, and if they do allow multiple installs(I think some will allow two or three installs) I'm definitely putting 2011 on this computer.
I'd actually not used 2008 on an Intel computer before today, and had hoped that it might not suck as badly as it does on a G4(and even a G5). Unfortunately, I was wrong. About the only thing it has going for it is the UI. 2011 ruined the UI with the "Ribbon"(although admittedly I can work pretty quickly with it now that I'm used to it) and is actually a(slightly) better piece of software than 2008. It's no 2004 or X, but with Rosetta support gone and my heavy reliance on XML, neither of those are options.
BTW, I also have SL installed on it, although I haven't done too much in it yet.
EDIT:
It looks like under the EULA of 2011 "Home and Student"(which is what I have, I think), I can install it on up to three computers that I own provided that I'm only using it on one at a time.
Since I'm the only one who uses my computers, and even when I use multiple computers I'm not running Office on them at the same time. It looks like I'm good to go on the '08 MBP. That means I can even install it on my iMac that's on the way if I decide to do so.
If I have the "Academic" edition(which I think might actually be what I have), if I read the EULA correctly, there's actually no limit to the number of installations although the same rule about only using one at a time applies.
My install media is at work(and in my old desk in the old lab, at that) so I'll have to find it tomorrow and see what I have.
It would be really great, too, if MS would come out with a new version of Office soon so that I can buy another copy!
