i have already a kindle 10th gen KT4 and want to know if there is a better choice in the market for using koreader and have great standard calibre support to send files (epubs) and remove them. my kindle kt4 is fine for my needs, i dont care about memory because i just mantain in the drive the books i'm reading and not the finished ones, the size is also great i dont know but maybe smaller would be nice.
pdf would be nice but not mandatory.
the problem here is that i live in Brazil and for what i have searched looks like there isnt any other ereaders that arent amazon kindle ones. kobo and liev seems abandoned here in brazil.
