Hi,
I have had a Kobo Glo for over a year now and it still works great. I have dropped it accidentally with no damage to the unit anywhere.
Yesterday, I was given the opportunity to pick up a pw2 for only $79 at my local bestbuy. Right away I noticed that the background on my glo is a lot whiter than the background on the pw2. The dimmer light on the pw2 combined with the darker background has me setting the light at over 18. (which is not far from the max setting) That is not a terrible thing.(and not everyone is like this)I think that it also has something to do with the fonts kindle uses. On my glo, I have added heavier fonts whick are way easier for me to see in dimmer light. I would have to jailbreak the kindle to add more fonts.(I don't think that it is difficult to do and I may try it later today) I think that both of these units are very similar but for me so far...I prefer me glo. I have 15 days to return the pw2 to bestbuy so I will give it a full weekand return to reply again with my verdict.
Hope this helps,
Penny
