I never owned a 2600 VCS (relegated to playing at the house of a friend with "wealthier" parents), but did become an Atari 400 computer owner/fan that I followed up through the STe and the company's eventual demise in the early 90's as they never learned of the need to update their hardware on a regular basis.
In it's heyday, Atari *could* have become Nintendo & Apple under one roof. Instead, a board of directors made up entirely of men in their 70's with no understanding of the fast-paced technology market doomed them to failure.
If this new company is looking to get back in the hardware game, they should seriously think about a MODULAR design that allows for easy hardware upgrades of everything from CPU, GPU, ram... even the MoBo itself (maybe that's the idea behind promising "PC" architecture?)
