Some more info regarding this $99 Nexus.
The company is currently working with Taiwan-based Quanta Computer to produce a $99 Nexus tablet boasting a single-core processor that will launch by the end of this year, Digitimes is reporting today, citing sources. According to the blog's sources, the tablet isn't being developed in partnership with Asus, the company that helped Google build its Nexus 7. The cheaper tablet is, at least right now, separate from the Nexus 7 lineup.
Does sound very compelling to me, more like a kid's tablet. A single core won't get you very far nowadays.
