Hey guys, so I upgraded from the 2010 MBP 13" to the 2011, and thought I'd post some observations between the two, for anyone thinking of upgrading: -First off, I did notice like many others that the 2011 MBP 13" runs noticeably louder than the 2010 on idle. I found this odd since iStat showed the fan was running at 2000RPM, and the idle temp of the i5 was actually 5C lower than the Core 2 duo 2.4ghz (iStat shows 38C idle, vs 43C on my 2010). After some investigating I isolated the noise to be coming from the HDD, in the lower right corner of the laptop. I replaced the 320GB HDD (the one in my 13" was by Hitachi) with my OWC 120gb Mercury Extreme Pro, and that fixed the issue, the MacBook now sounds identical to my 2010 at idle-moderate usage. (I haven't stressed it with any games yet). I have had other laptop HDDs that make a similar fan-like noise like this one does, but this one is considerably louder. -The new MBP feels MUCH cooler under moderate load compared to my 2010. While installed Windows 7, my 2010 got pretty warm on the top right and top back of the laptop. The new 2011 barely got warm at all. I did both installations at the same ambient temp. -The keyboard on the 2011 feels less stiff than it does on the 2010. For me this is a plus since I found the 2010 keyboard keys to be a bit too stiff. -The screen at max brightness is brighter on the 2011 than on the 2010, although I beleive this is one of the same screens used in the 2010 (both model ids on the 2010 and 2011 are 9CC5) -The SuperDrive in the 2011 is quieter at bootup and ejecting than the 2010, It also seems to be faster than the 2010 superdrive, although this may be because of the processor. -I can't tell the difference in video quality between the 2010's iSight and the 2011's FaceTime camera. -The wifi on the 2011 seems to be better than the 2010. (will have to test this) -The 2011's keyboard backlight is brighter. I don't really like this - I think its too bright, good thing I can adjust this. -Happy to see that the RAM used inside my 2011 is hynix, my 2010 macbook has samsung. (hynix is considered one of the best RAM manufacturers, samsung is probably good too though). -It's FAST! If you wanna know anything else Ill try to answer.
