about the 2010 model:
Is the vendor providing the licenses for Lion, Windows 7 and the CS5 suite? If not, I would be very careful, since he is illegally using the installed software to increase the price.
It has applecare, which is nice. If it doesn't come with the licenses, I think $1600 is too much.
Not to be rude, but please use some logic here. Even on Amazon it's $2320 for that software package not including the Windows license. If it was an oem license of Windows from Newegg it would be useless to the seller after that so I could see him including it. No one is just going to give away their creative suite license. I don't personally care if the OP uses it, but it should in no way be reflected in the price paid for the machine. FYI I don't own one of the suites. I only own a couple of the programs, and I only bother upgrading if I like the release (or if it gets far enough back to where I have to upgrade or lose eligibility to do so later).
I know what you mean about the CS5.
We bought the academic discounted version for my son who is going to school. I know we have to deactivate it on the machine it is running on in order to install it on another one. In the end we could remove it from the desktop it is on now and move it to the mac.
The guy wants $1600.00 for this one.
He's asking too much in my opinion.

This was a dual core i7. Note in laptops there's no difference on hyperthreading between i5 and i7 at least in Sandy Bridge. Look at this now.

Note that's a Sandy Bridge quad core version with a better gpu for $1359 in the refurb store. I know it isn't present in some of the tests linked, but the 2.3 sandy bridge, while more expensive, isn't that much faster than the 2.0. Basically if they're running cool enough their turbo boosts cap out pretty close to one another. Anyway it's significantly faster than that one at $1600.
Applecare is around $350 for the 15" macbook pros, and then of course there's tax, but my point remains you could get a faster 2011 in the same price range.
Also one last thing I need to mention. With a used computer that has applecare, make sure you get some kind of a receipt or something so they can't cancel it once they hand you the computer (as it is partially refundable to whoever bought it), and remember that applecare doesn't cover any kind of accidental damage, liquid damage, etc. This means that you need to be sure of its condition when you buy it. I'm not trying to make you paranoid, but I wanted to point out stuff that some people miss.
