Many years later - actually in the late 90s - I bought a Falcon although by that time, PC's had completely taken over so it was more of a nostalgia purchase.
It is in this timeframe that I acquired my ST, as a compensation for PC repair services.
I've been PC guy all my life, having limited contact with C64, seeing Amigas at friends houses, etc.
For me it was interesting to retroactively compare this "new platform" against something I've used from same age...a PC-XT, and from a position of having a bit of knowledge how things work. I knew I should expect absolutely superb graphics experience due to blitter and a proper sound, and that machine by its form factor is harder to upgrade.
I've been impressed by looks of GEM and how everything (TOS - GEM and GEMDOS) are in the ROM. The machine didn't POST for half a minute then clonked up the HDD to slow through autoexec - it booted swiftly and silently into a GUI.
The easy upgrade to 4MB...I searched the Internet back then how to get rid of German operating system, discovered SELTOS, but my machine only had 1MB RAM...Opened it up for the first time, saw bog standard memory slots, brought a bag of memory from cache, put some modules in, it boots to 4MB, SELTOS boots into US TOS. True happiness.
Less so impressed by the video switching. My XT had a monochrome monitor and works in high resolution mode by default, but perfectly able to show CGA games. Sure today I'm aware why it was easy for that XT to do so, and why it would be hard for ST, but from just user's perspective back then, it seemed like an extra nuisance.
Completely dissapointed by the keyboard. I found it much more comforting to work at any generic PC keyboard than Atari built in. Are Mega keyboards better, or same?
All in all it is a wonderful machine and biggest surprise about it, for me, that it was designed and sold as a lower cost machine. I've always seen it likw an Apple but more for sound than for graphics.
