This one is definitely, definitely, firmly in the rumor bin, folks - and if history teaches us anything, it's that in the Android community rumors tend to stick to the lines of "Somebody tells you something somewhat ridiculous, but plausible. Post. Watch it spread like wildfire." Still, sometimes we get things right, too, and with that in mind, I present to you the Dell Opus One.
AndroidPolice render of the Dell Opus One
The Opus One was leaked by somebody who attended a private Dell presentation. Supposedly scheduled for release in May 2011, the phone/tablet is easily mind-blowing on paper: it features a dual-core 1.2 GHz CPU and a 1280x800 ("or somewhere in that range") 5-inch screen. StreakSmart theorizes that the CPU could be a next-gen Snapdragon, which could certainly fit.
Sound too good to be true? It probably is, especially given just how little we have to go on here (again, this is from an anonymous tipster who couldn't provide any proof), but you never know. At the very least, we can dream, can't we?
