In Microsoft's defense (dangerous here I know) the vast majority of Vista problems HAVE been resolved months if not years ago. Further, most of those were hardware issues (nVidia..) and sloppy programming of other programs and thus NOT Microsofts fault. The single biggest obstacle it faces now are uninformed customers who heard "their computer guy" tell them two years ago that vista = evil and now refuse to listen to anything otherwise.
Sure there are some that still have problems, but most of them would have problems on a computer no matter the OS. Vista as it is today and during the mojave ads is actually very nice.
Microsoft acknowledged their problems (even though they weren't actually at fault), resolved them, and then tried to inform consumers that they had been fixed. Apple is rather just saying its not our fault to begin with.
