Girlfriend has a 2008 MB that I bought off Ebay, other than the hard drive dying (and giving me ample warning and time to replace first), it's had no problem. Since it's limited to 4GB RAM, it isn't really ideal for development, but she runs Photoshop and Illustrator on it (albeit, a bit slow for my taste).

I personally own a late 2011 MBP (same as the article, I believe) with 8GB RAM, also no problems, running a pretty standard development set up.

I have another 2012 MBP through work which is a bit beefed up, though still nothing fancy. Also no problems. Also manage a couple of 2010 Mac servers there which have been running steady since late 2010.

Oh, and none of these have SSDs. So, say what you will about non-SSD, they work well enough for development.

All in all, have to agree -- whatever fits your budget, at least in my personal experience, will work pretty well. I know that people do certainly have issues with them occasionally, but when I compare my luck with them to my luck with various other brands (Compaq, Dell, etc), they've lasted significantly longer with few or no problems.
