Ha ha! That's a very interesting attitude you've got there. It's not Microsoft's fault for producing buggy, data-eating code, but the user's for being stupid enough to use the software that he paid good money for. <sarcasm>"Oh thank you, Microsoft, for letting me give you money and then corrupting my hard drive."</sarcasm> #fail
In actual fact DOS 6.0 was a serious problem for Microsoft. They had to release two/three updates pretty quickly in order to fix the doublespace bug (6.2) and changing the code to avoid infringing a 3rd party's (stacker, was it?) patent (first by removing doublespace in 6.21 and then reimplementing it in 6.22).
DOS 6.2 was a great OS (for the time) and was the last piece of software that I paid Microsoft full price for. I bought a 'discounted' copy of Win98 in Malaysia and more recently an OEM version of XP (for use by my wife in a Linux VM) on ebay for ~£12.
