Re: If you're going to include games consoles...
Okay, your point holds- you can connect a mouse, keyboard, local storage and an external monitor to both the PS3 and SG3 to satisfy some definition of 'computer', but personally I find the SGS3 to be a little generic-looking to be featured in a 'top ten sexy' list.
Curiously, the original Playstation was a deliberate homage by the Sony Design Centre to Frog Design's work for Apple... especially the use of grill-like lines in the casing. Frog have worked with Sony in the past though, since they worked with Wega before Sony bought it. And having just looked at their site, I see they designed my first ever mouse, a Logitech that came with an Olivetti 8086.
I visited their NY studio once, and on display was a 90s-era black cast-magnesium PC case with the same ridges... only this time more functional as the case itself would act as a heatsink. I can't remember who the client was, I think I just assumed it was IBM.
