Anybody seen an OS shrink in size? I'm not aware of it. And as far as size, functionality, speed and multi-tasking, I have yet to see anyone come close to BeOS. Pity that Apple didn't choose to make that the core of OS X. (Almost happened before Jobs came back. BeOS was written from scratch as a multi processor, multi-tasking OS that booted my Pentium II machine in 30 seconds.)
