Below is the eMail I got back regarding what v1.3 update brings us, and if it fixes the touchscreen...
Response Via Email (xxxxxxxx)
Thanks for your recent email.
Hudl v1.3 includes an improvement to WiFi performance, improvements to the reliability of App updates and our latest versions of Tesco apps and widgets.
We have had no reports of installation of the update causing units to fail.
As with most software updates they are released to resolve issues and implement improvements.

So as you can see, it's rather vague and generic....
I failed to mention of the Root access.... (lol) And no mention of the Touchscreen issues...
So there we have it, least they replied... But still, we assumed that's what it would cover anyway. No specific details.
