AmigaOne is a cash-in on a very dated trend. PSOne is obsolete. MediaOne is gone. You're either a leader or a follower.
At least they didn't call it the iMiga.
They should call it something new every time they redesign the mainboard. I still cringe whenever I hear people try to describe the PowerMac G3 towers, and they have to call them either "Beige" or "Blue and White". Sure, let's have a whole lineup of computers, over a couple years, all called the same thing. I feel the same way about AmigaOne and AmigaOne XE.
I also think the whole OS should have been renamed to Workbench. AmigaOS just sounds so... difficult.
