MS has to much money for any of their products to dissapear.
That does not mean everything,
thats one of the biggest mythes this generation
MSN, failed in a sense
it was losing too much money from the rebates for service that they had to cancel the plan
Ultimate TV failed, they also quit supporting it also
WinME in a way failed, it was much lower in sales then previous MS software.
Its not logical for a company to continue to support a lost cause and lose billions of dollars, even if your MS.
Stock holders do not apreaciate that.
