Re: No talk of the known issues on this device?
If I'd come across either of these issues (or any others) I'd have reported them.
The GPS radio has worked perfectly every time I've used it, including for a solid two hours as a satnav. The same goes for your touch-point tracking issues, it simply was not an issue I encountered on my review device. I can't criticize a device for a glitch that in my personal experience doesn't exist no matter what you or I may have read elsewhere.
As for the thoroughness of the review, other sites will be able to provide you with page after page (after page) of interminable bench test results if that is what floats your boat. That's not how El Reg's consumer tests have ever been done, I approached the new Nexus 7 in the same way, and with the same critical thoroughness, as I did the Xperia Z Tablet, Galaxy S4, Asus FonePad etc etc etc.
As a device I think it's pretty darned good, especially for the money. My review reflects that. Fell free to disagree.
