The modern wonder that is Microsoft BASIC
>> "Billy boy and co wrote Amiga BASIC for the Amiga, and god damn it was awful! It made lots of Amiga users glad they never developed virtually anything else for the platform!"
That brings back painful memories. Gates' BASIC made my first computer, a Dragon 32, a laughing stock with the contemporary technology press. At the time I thought that they were just being rather mean spirited towards the Welsh wonder, but the inevitable reality gradually dawned that it was indeed encumbered by a spectacularly crap version of the language compared to many of the other pre-IBM PC home computers. My realisation that Microsoft's products tended not to live up to the hype was a lesson learnt the hard way.

DEC fell victim not to Compaq's taste for acquisitions, but inept management: after the board inexplicably (or at least too hastily) replaced Olsen with the visionless Palmer, the only way was down. Very sad, really, a lot of good technology sunk with it, but they were too busy with in-fighting and endless reorganisations to bother with apparently tedious irrelevances like customers. Who, ironically, were often lining up to buy their stuff only to find that they couldn't even beg DEC to sell it to them under Palmer's regime.
