I used WinME since 2004 to 2008. Very stable in my computer... ermh, was I lucky enough???? My PC at that time was an Intel Celeron 333 MHz, 128 Mb RAM, 10 Gb HDD, integrated soundcard/video.
Fairly reasonable remark. Thanks for sharing! Well, OSs are the most complex software ever, so it's not difficult to meet those strange failures in function of hardware available at certain time. ^^
