An anonymous reader asks: "Well after the long torturous wait, Vista is finally out. Is it just me or do others see similarities between Vista and the OS/2 launch back in the '80's? I mean you need new hardware to run the new OS (Just like OS/2). Even on the best '386 system OS/2 still ran like a dog. Older apps sometimes didn't work (DOS penalty box). And most important, what was the compelling reason to upgrade? Add to this an interview I saw with Ballmer, some time ago, where he was talking about how he knew OS/2 was doomed when IBM kept talking about OS/2's KLOC's (thousands of lines of code), and how bloated OS/2 was. Now I see an interview with him where he talks about how great Vista is due to the, yes you guessed it, the KLOC's of code in it. So is Vista going to see the same fate as OS/2?" This is kind of a hard sell seeing that Vista has Microsoft's might behind it, rather than against it. Still, how long do you think it would take a good percentage of computer users (say 80+%) to migrate to Microsoft's latest and greatest OS?
