Hellow,
@ xendula & @ davidfor : I have Calibre in my netbook and so far, I haven't really used it, but hope once I get my eReader, it will play an important role in my ereading experience
Thanks a lot for your help guys, I guess, I will go with Kobo even though the customer service, somehow, has a minus point compared to Amazon, but we'll see. I guess, no eReader is perfect and hope Kobo will get a love from me
This is a tricky thing actually but I hope I made a good choice
