I last week I tried to use Windows. I needed to interface with a piece of lab equipment to do current/voltage analysis. I tried to do it the 'right' way and acquired a university-owned box and had the IT people install LabView and other expensive vendor-specific software that I get for free. After messing around with the IT people for a couple hours trying to figure out why the windows installer was corrupt and I couldn't install my GPIB card drivers, (on a brand new install), I realized I now had root permissions, so after the IT people left I gave up and installed Wubi.
Once running a real operating system I was bypassing the GPIB interface entirely by echoing commands using the serial port...it's rather quaint using a quad-core workstation as an absurdly powerful teletype, but at least it's simple and always works. By the end of the day I had a Perl script to fully measure and calculate all relevant solar cell parameters, write the data to a text file, plot the I-V curve with proper dimensions, generate a .png image, and use LaTeX to format a nice pdf page with a graph and the data formatted in a nice table and plop it all in a new directory, using rsync to mirror it elsewhere. All this because it's so easy to just pluck software (feh, gnuplot, latex, dvipdf, pdftk, and on) from the trees and pipe things into and out of programs like it's going out of style. Perl makes it so easy to run command line arguments it makes the evil hacker in me cackle with glee. Using linux is like being plopped into a junkyard with a Sawzall and a MIG welder. I don't know how to get anything done with Windows.
