NOT one of the top 25 PCs of all time, but my first (1986).

[Christian4Bush]

Like many PC model designations, AT stood for something--and no, it had nothing to do with the Imperial AT-AT walkers featured in The Empire Strikes Back. The term was short for Advanced Technology.

Is the phone included?

That actually looks pretty sleek for back in the day.
I was around then, but I didn't get into pc's until about 95.

[Dont Mention the War]

The first-generation iMac of 1997 may have been the machine that told the world that Apple, and its recently returned cofounder Steve Jobs, were back. But its second-generation successor was a vastly different, far more inventive computer. And even though it didn't turn out to be an influential one, it remains a high point in PC design history.

And it is without question at the very top, numero uno, of the list of Most Annoying Computers To Repair Or Upgrade Ever. You have to take the entire machine apart just to swap in a new hard drive. Then you have to actually get it all back together again, which is damn near impossible and actually requires you to apply thermal paste.

It's cool that I was an engineer that worked on creating several of these items...

[antiRepublicrat]

My first, little brother of the 800 mentioned in the article:

Had 16K RAM, membrane keyboard, tape drive (as in audio casettes) and an external 300 baud modem.

My first was the commode 64

My favorite:

IBM PS/2 Model P70

While PS/2-P70 was the official name, everyone called this machine the "Luggable." It came along around 1988 or so. An Intel 386 CPU, 4MB of memory and a 30MB hard drive, and a 3.5" diskette drive. The display, which folds out from the unit, was monochrome, with a weird orange color (like this.) IBM called it a "Gas Plasma Display." This system was "portable" if you had a strong back (it weighs about 20 lbs.) and a place to plug it in --- no batteries here!
