The issue with the T07 is mostly overheating, MeeGoPad told me that Z8300 CPU is too hot so they made an upgraded version of the T07 4G wich is called "T07 4G (Z8350)"
To answer your question...
Heres a specs list:
T08 doesnt use the same CPU as the "T07 4G (Z8300)" but uses the less hotter CPU "Z8350"
I'll asked why they switched to the Z8350 CPU, a MeeGoPad representive told me that the Z8350 CPU fixes alot of problems wich were present with the previous Z8300 CPU.
I'll cannot say for sure about the "suddenly-turning-off-issue", but i'll guess its atleast less hotter.
