Tnx for your reply,
I am actually very disappointed with my device that is a Kobo Arc 7. It is sold as a reader and Tablet but you can't import pdf files to the library and read it with the Kobo's reading program that gives you all the text modification features, background color features etc. Also there is no "documents" folder to access your files. No access to sd card either. No Google Cloud Drive icon present on the desktop either! The only way way to access all that is through "Office Suite" that makes non sense and it is very non practical. To bypass the problem that I had i.e. reading a pdf book and modify the layout, text, color, bookmark option etc., I had to download an app called "SmartQReader" which is awesome by the way!
My answer is a little lengthy but I hope it answers your question and refrains you from buying a Kobo.
I was trying to be sarcastic about the kobo, Gosh you geeks have no sense of humour!
