I got my (and my brother's identical model) MBP there. The people there were very nice. I started off with an open-box 2.26GHz model. I left there and paid around $1029 for the whole thing with a MDP-VGA adapter. I was happy. Then the 2.4GHz models came out abut 9 days later. I took it back and exchanged for the 2.4GHz model and paid an extra $100 or so... And the guy who originally helped me, helped me that time.. I didn't have to pay any restocking fee. Then that machine decided not to wake up from sleep unless I dragged a small magnet over the sleep sensor. I took it back to Best Buy. I saw the same sales associate there who originally helped me. I explained to him the issue, and he handed me a brand new machine. I was happy. But then this machine decided that the backlit keyboard did not exist (and this was about a week after purchase). When I had my finger over the ambient light sensor, the backlight would not come on. I hit the backlight-up button, to no avail. I reset SMC, PRAM and even booted into safe mode. Nothing worked. I took it back, and to my luck, I got the same exact guy who helped me in the first place. He was understanding, and wanted to attempt to reproduce the issue (and getting tons of fingerprints on the screen). He was successful. He handed me back a new machine and I left there happy.
Fast forward to about 3 months ago (about 7 months after the initial 2.26GHz purchase): the control key decided to fail, and the machine decided not to go to sleep. I took it in to the Genius Bar, explained the issues, and the genius was very understanding. I even explained how my battery was at 89% capacity after 230 cycles and a battery calibration, and how my HDD always beeps randomly. He said he would note it.
About 8 days later: I got the machine back. They had replaced the topcase, battery, HDD, HDD cable, internal speakers, and magsafe board.
Then about 2 months or so after that: I noticed dust under my screen (which I suspect to have been there ever since the replacement machine [from best buy] was handed to me). I took it to the genius bar, along with a couple of MacBooks that needed firmware passwords to be applied. The genius and I spent about 10 minutes doing so. When I explained the issue with dust under my MBP's screen, he said "oh. We will need to send that to the repair depot; we can't do that repair here." It sounded like he didn't want me to get the repair done. I said "I know. It's okay. I have all of my information backed up, and I can afford to be without the machine for a week or so." He said fine, that's what we will do. I got the computer back about 5 days later, and they had replaced the entire display assembly! But, even though I had them note that I had a firmware password on my computer and what it is, they reset my firmware password anyway.... ARGHHHHHH
Edit: This thread made me grateful for my 3 years of AppleCare, so I added it in my signature.
Edit 2: Oh and my current 2.4GHz MBP was purchased on 4/24/10. Almost 10 months!
