Yes, it is (technically 31 from the IPO, but it was active as early as 1975 with the the two Steves building the Apple I, but officially it's 32 years old) and until about two years ago I hated Apple, mainly from ignorance and the hate of conforming to the "iPod Nation", but changed my mind when I got one. It was one of the best things I've ever had. In only minutes I want from a kid who hated Apple simply for it's popularity with the iPod, to an Apple fan-boy. Soon after, I became a hardcore Macintosh fan-boy, with a passion. I hated Microsoft for about a year, until some personal events took place and I've grown to acccept them as an decent company, though still second to Apple, but it'll still be a few years before they're legitimate in my book.
Along with the "under 30 = worthless" idea, two years ago, Apple only had about 8-9% market share in the computer industry, in the time since then, they sky-rocketed to a current Market share of 19-20% (with a whole 3.5% in the past 3 or 4 months).
IBM was thirty years old (about, I'm not going to look it up) when they released the IBM-PC, it sold for $10,000 and outsold Apple's Apple ][ (the only competition) which sold for about $1,500 by almost 80%. All of this supports the equation: Company > 30 = Success.
