they don't like it when you spoil their party.
First they claim that the Mac had it first, then they will say that some other platform before the PC had it first but it doesn't matter that the PC had it before the Mac.
Quicktime, buggy as it is, always beats DVD players in their book.
They completely ignore the Cuecat, free device that Radio Shack gave out, improved the UI by allowing users to scan in bar codes to go to web sites. Sure beat typing in [link|http://www.radioshack.com/|http://www.radioshack.com/] to the browser and then searching for the item they wanted instead of scanning it from a Radio Shack catalog and jumping right to the site on the website to buy it from. But no, it wasn't on the Mac first, so it doesn't count. Or they will try aad say that it wasn't a true UI improvement, or that it didn't matter. As far as I knew, it was only PC technology, it used a PS/2 keyboard port. But they did invent a Linux interface driver for it.
Oh yeah, let's ignore the PCjr, because it was just a piece of crap. It didn't sell well at first, like the Original Macintosh. One of my friends actually got a cheap PCJr from a surplus sale and they threw in a free 300 baud modem with it, he was able to hook it up to his TV set and play Tradewars and get on BBSes way back when. To him, it wasn't a piece of crap, it worked as advertised. All he did was get a copy of Procomm, and zing, off he went. Software was easier to install/use on the PCjr than the regular PC, as some games came on cartridges. You cannot beat just plugging in a cart and powering the system on for an easy install. Plus the Sidecar expansion on the PCJr had a primative plug and play technology, this was before the Mac, and at a time when all the Mac had for expansion was serial ports (Before SCSI, and ADB) and that floppy port.
The Amiga pinoneered high color displays and desktops. It had 4096 colors, when the Mac still worked in shades of grey (on its built in monitor) and the best that IBM had was 16 color EGA. The Amiga also had a built in speech chip and an API to access it. Amiga BASIC had the first interface to it via the "SPEAK" command, and other languages had built in support for it. But it doesn't matter, because it was not a Macintosh?
Let's not get started on those HP systems and the touch screen that they had, oh no. It predated the Macintosh and the UI made things easier to use by pointing at it with your finger. No points there, even if it did use 3.5" drives before most other PC Clones.
