I found this question on the Swedish book blog The Cabinet of Miss Magic and I thought I'd reply to it.
It's not all that long ago that I went to Riga in Latvia. Naturally, I wanted something to read on my trip. I brought my phone (which works fine as an improvised e-reader) and my surf pad (that I tend to read on a lot). However, I didn't bring my e-ink devices or any printed books. In general II don't like to bring too much luggage. The less I pack the less I can leave behind or lose some other way.
