Do I go for the Konica AR 50mm f/1.4 or the Contax Planar T* 50mm f/1.4? Contax is very likely the better lens, but is $250-300 more expensive. I can afford it mostly, and I do sort of regret cheaping out and getting the Konica AR 40/1.8 instead of the CV 40/1.8 I really wanted, but it would save a bit and should be a good, maybe even great lens. Canon is out as I hate their bokeh, and I haven't been thoroughly impressed by the offerings from anyone else not named Leica.

Also, do I write my senior thesis on factors preventing nonprofit organizations from adopting open-source software, or the relationship between open-source developers and proprietary/commercial developers?

I'm currently struggling with the first question to avoid the second...
