Just received the Kobo Glo HD.
I like it a lot, its sturdy, almost the same size as the Sony PRS-T3, but then with a better screen and background lightning.
IMHO it is also more responsive (quicker) then the Kobo Aura HD, so that is a bonus. Further, it is advantageous that the look & feel of the GUI is already familiar, so one can start quickly.
When it also exceeds its warranty period, then I'm a happy and content man
