For my serious comment I will say:
The reason any one would assume that an "all-in-one" computer would be knocking off of Apple is because Apple has done them very successfully for years. Everyone knows of the iMac, they don't know about the lesser known designs by lesser known companies. It's not that Apple did it first at all, they just did it successfully for almost a decade with no major problems or loss of major profits.
This gateway is better than the iMac in regards to design only because it can be upgraded by the user, while the iMac is still pretty much locked in. BUT, the market shows that many users in the consumer market (which this machine is built for) don't care too much about upgrading their graphics cards or any PCI slots of installing a second HDD. The iMac has caught flake from those that wish to upgrade its parts for years but Apple is still selling them rather swiftly. The iMac is the best bargain in Apple's lineup.
The reason many consumers go for PCs rather than Macs is because they want a tower that they can upgrade in the future. The only Mac tower is the Mac Pro for $2400, while the PC industry has a plethora of towers and cases that can be upgraded or built up from scratch. Gateway should really stick to that market since it is what is keeping many from switching from PCs to Macs.
My final ruling... this Gateway One is a nice tester for the PC all-in-one market, and does a better job than the others. It offers more customization than the iMac, but that isn't what all-in-one users really, truly want; especially given the price for the specs. At $1799 I can get the 24" iMac instead of a 19" PC and just deal with the pain of not having two PCI slots I won't use. In other words.... it's gonna be a Palm Foleo, right product at the wrong time.
