Using a Kindle/iPad/laptop really helps with ad nauseam dictionary lookups, since you can just tap the word and get the definition right there. The Kindle even saves looked-up words to a vocabulary list to help you remember them.
By default, this only works for advanced learners. The tap-to-define action shows a same-language definition, and not a translation into your native language.
If your comprehension of the text is 50℅, you probably won't get enough from the same-language dictionary definition.
IIRC there are ways to hack around this, and install a bilingual dictionary to replace one of the Kindle's regular dictionaries.
