It's not unusual for Chinese companies to release clones of phones or tablets before the original product is even released, but generally the clones have been inferior in pretty much any sense to whatever they're copying. The fake Dell Streak manufactured by a company named WellDone is a 7" tablet that makes phone calls and bests the Streak in the spec department. Read past the break for more info and hit the source if you're feeling especially lucky.
So the unnamed Streak clone has a 7" resistive (eww) touchscreen with the typical 800x480 resolution, but does come with a 1.2 Ghz single-core Cortex processor, 512 MB of Ram, Gingerbread 2.3 - without Dell's custom overlay, but probably also without market access - a bigger 3000 mAh battery and it can make phone calls. Not sure why you'd want a 7" slab of glass on your face, even for short calls, but it's there. It's definitely nothing to write home about, but for ~$200, if you're in the market for a decent-ish tablet, it might be worth considering. I wouldn't expect custom ROMs, updates or customer support for it, but if you're into tinkering, it's your call. The source holds the link, but don't say I didn't warn you if you're not satisfied.
