From purely personal experience, I did know someone with an Atari 8bit, which is much more than I can say about the Oric, Dragon, Enterprise, Jupiter, etc.
That's okay. All of my friends families purchased C64s because they were involved in massive pirating ring at the time [yet the Atari 8-bitters were always accused of piracy; I don't believe at all it was anywhere near proportionately what was going on with the C64 user base]. I wanted an Atari 800XL but then the whole game industry crashed, Atari was in doubt, and then the ST line came out and so I asked for that and my parents bought the 1040ST for me. At the time, early 1986, it looked like Amiga was going to crash because it was deemed too expensive for the standard memory and they didn't recover until the A500 started selling well. Looking back, I really wish the ST and Amiga lines would've been merged following the out-of-court settlement between Atari and Amiga. I have a feeling that such a platform would've survived to this day and so there'd be a serious third platform challenger for those who detest Microsoft and are sometimes fed up with how Apple does things.
I should also mention that I didn't meet any Atari 8-bit owners until I joined the local combined Atari users group which catered to both the 8 bit and 16 bit owners.
I was an AVID Atari fan! I owned the 2600 and the 5200. The Atari 800 was my first computer. I can remember all-night sessions logged into pirate BBSs via a 300 baud modem, downloading every disc image in sight!

Later, I was a huge fan of the Atari ST line. I met Jack Tramiel and his sons multiple times at various Atari user conventions. In fact, the Atari ST is what led me to become a Macintosh enthusiast...
Don't get me started on that bunch. When "you" - meaning "I" - was only 14 years old and was asking pertinent questions of the CEO at the shareholders meeting and you have the majority of the present shareholders on your side and putting the CEO on defensive over boneheaded business decisions that they've made, there's something truly wrong with that picture. That and making the Time Warner rep goons look dump in the process with their $2k business suits.
David Small ("Gadgets by Small") invented the "Magic Sac" Macintosh emulator for the Atari ST, I became an immediate fan. I took to sharing my enthusiasm on both Compuserve and GEnie and, ultimately, was invited by David Small to be an official (paid) product support specialist for the Magic Sac and, later, the Spectre 128 and Spectre GCR. Back then, a color Mac was what I really wanted but the the full-blown color Macintosh II system was $10,000!!! Yikes! But, eventually, Atari Corporation started coming apart at the seams and Apple released less expensive color models. When the timing was right, I purchased my first real Mac.... The Macintosh LC in 1990 or so.
Ah yes, "the Magic Sac, turns your Atari into a Mac!" And with that, the Atari STacy became the very first Macintosh portable computer. I bet not too many people on here know that little tidbit.
I didn't go Mac - and only partially at that - until 2003. After being burned when Atari failed, I swallowed my pride and went PC because Apple looked like it was going the way of Atari and Commodore at the time. Thankfully, Apple has rebounded but it still cheeses me off that there's no Atari or [credible] Amiga option today.
Yeah, it's odd to hear people complain about paying $1 a day for mobile broadband... when back in the day, we had 300 baud modems that would take several hours to download a 1MB picture... at $5 an hour on CIS !!
And you were glad if the nude pics were actually pics [scans, not "artistic" re-creations] in 16 colors! Pre-emptively shut it, former Amigans, with your fancy 32 color graphics and HAM trickeries!
Thanks for all the great feedback and comments. It has brought back so many memories even for ourselves. And just seeing the discussions about Atari, Amiga, C64 - it has had a great effect of those old school-yard discussions (or arguments)

Well, since I don't own - shudder! - an iPhone [yet], I don't think I should contribute to that link but any Lucasfilm Games/LucasArts title would be awesome. I'm still trying to picture how
Ballblazer would work on the iPhone.
Others have mentioned Jeff Minter. The man has been developing stuff for the Xbox 360. He hasn't come to his senses yet about the PS3/PSP so who knows what he's up to with the iPhone. I guess I should stop typing and go over to his website.
