STATA 11.2 SE runs just fine on the notebook (and the MP license works fine for an SE installation, as I verified with STATA Corp). Honestly I'm not fitting insane models with matrix sizes of 5000 or else I would appreciate a faster machine, but scripting, data management, graphics creation, and simple regressions and analyses are totally acceptable using this hardware and 500MB of RAM dedicated to it. I can do tons of stuff. I am so happy that STATA Corp continues to support the PPC. As long as the machine works, I will do all of my mobile analysis with this platform. Oh, and let me say, having the 1400x1050 resolution is so helpful for that program! I trained as an economist/policy wonk at a place that uses STATA heavily, but now do university administration.
Yes, I use TeXShop, which seems to work fine for what I need it to do.
