It does not get hot at all.
For me it is simply perfect, I convert jpegs in a html web gallery using "express thumbnail creator" or "web picture creator" and read comics using internet explorer...the main problems are :
-it is not easy to read in a sunny day (thats a problem in Spain

), but it is perfect to read in the dark.
- it takes 3 or 4 seconds to go from one jpeg to the next one in the biggest pages.
- is not comfortable to carry one of this with you the whole day , I am looking for something smaller to carry in my pocket, to read everywhere...maybe words gear
