with powershell, now even have a very respectable command line.
with windows7 now finally have a modern OS? may be, the jury is still out, i have been using it on my home install, so far so good.
i have been slowly but surely moving towards doing more and more hacking in F#.
have even been using it to get real work done - but so far these have been scripts in the 30 - 100 line range. even did a presentation at work about it!
