Apple's Magic Mouse. Led to all sorts or ergonomic problems with that took months to fix (effectively couldn't use a mouse, period, for months and was limited in how I could use the arm). Juxtaposed: the magic trackpad is a truly terrific piece of kit.
Previously was using a OCZ Vertex 2 Extended and it worked fine. Now running with a M4 512GB and I'm happy, though the first M4 I received was DOA. Lots of warnings in the Crucial forums about problems with the M4s and early 15" 2011 MBPs, but apparently moving to the 0309 FW fixes most problems.
I'd say it depends on the system you're putting it into. The Crucial forums are filled with people who've had problems with the most recent firmware for the M4s, especially if you're putting it into an OSX machine. From my own (entirely anecdotal!) experiences, I'm not sold on the M4 just yet...
Absolutely rely on it. I suffered extreme pains in my right arm from using the mouse so much, and since switching (for past 6 months or so) pains have vanished. Means that I can't game or anything, but for daily computing the trackpad is awesome.
Yep - hopefully done the PhD in another 18 months or so (I focus focus on telecommunications, surveillance/privacy, and regulatory regimes in the UK, Canada, and US).

I'm presently looking to purchase a 15" MBP, and have the option of buying a 2010 2.4 GHz base model for $1,319 or a 2011 2.0 GHz base model for $1,599. The key thing that I'm interested in is the monitor size (I'm losing the office space I presently inhabit, and the 24" screen accompanying it)...
The WebKit bug that was taken advantage of in Safari had already been patched in Chrome; there was an exceptionally long discussion this year at CanSec about whether or not going after a patched bug could give you the pwn. In effect, Google's highly aggressive patch cycle protected their...
Only time that I hear my computer now is if I'm beating the hell out of the CPU or GPU, or (obviously) using the optical bay. As someone who spent a fortune years ago in silent (PC) computing, this is almost at the point of nirvana :P
