I agree that running a simple web site is not a compelling enough reason to switch to Linux. However, I cannot imagine doing any development without command line. IDEs are nice (be it Eclipse, MS Visual whatever or this-or-that builder or what have you), but good shell and Unix utils are absolutely indispensable. What can poor developer do without shell/find/grep/sed/awk and their cousins!? I personally have Cygwin installed on all my Win boxes, but there are other similar kits, including one from, gasp, the Evil Empire itself.
