e-book reader for Thai with English translation?

looking for recommendations, looking up words from a paper book is too inefficient. I live in Thailand but couldn't find anything in my local mall. Ideally I'd love it to have an option to highlight words and translate whole sentences, but it's not a must.

on a side note, I've never had any of these things, can you run android on them or do they have their own OS mostly? android would make it easier functionality wise. curious to hear your experiences
