If you are not dependent on any special Windows-only application, you can get the freedom and speedy feeling that Linux can give (smile == no religious OS war intended/wanted)
Reading your mail made me philosophical, forgive me but...
I also like my computer and software to be quick and "to the task", and it wonders me how much more "extra work" the poor computers have to do all the time, as they get qicker. If you work twice as fast, you will have to do twice the work!
When something takes to long time, you ideally want to optimise that part. You can not eliminate all work in life, if you, for example, are to show a series of 4 MB large images, you will have to transfer them from the disk to the main memory/graphics memory. But it is my feeling that a lot of bits and bytes are beeing moved around without any purpose. Of course it might be easier to write programs and operating systems that way, which is then a valid reason.
Even so, if you are like me it is hard not getting amazed by Chuck Moor's ideas present in ColorForth, a favourite read of mine!
