Hi! I decided to make a post here since i'm going all nuts in doubt picking one of the above. Not that I haven't the posts around, I have, I’ve been reading everything I can on both models and i just get more and more confused

.
For me positive points about kobo:
- Higher res.
- Light.
- Better design;
About the Sony:
- Better Dictionary;
- PDF reflow;
- Runs on top of android;
Points to consider:
-I don't know better the experience can be with the higher res. screen, specially considering i already read sometimes on my prs 650 on the smallest font settings and it was ok.
- I was never much a dictionary worm, but the oxford American dictionary on prs changed that in me, I don't feel so confortable since the kobo's dic apparently have a lot less information (although i could just take quick looks over it on video reviews). Can anyone comment on this?
- Fact that prs t2 can be rooted is a big plus, since it could run lots of stores app. (I'm sure right now it must not be the stable-est thing to do, but with time i guess it will become more stable? Should I hope for this?). I consider I have some experience rooting/swapping roms/kernels of android, since already did it in a xoom, kindle fire and 2 phones);
Any general opnion to shed some light in my indecision?
--------edit
Forgot a important point:
How's Japanese suport on european kobo glo/t2? Do any get any dictionaries or are able to display jpn text vertical?
