Looking for an ebook both for reading (must have sleep function and of a practical size) and referencing data sheets and reference material (must have easy sorting of documents and search feature). Any ideas?

Thanks

Reference material, too? Then go for a notebook or for the iRex iLiad.

Careful with your terms, there. Letting an eBook user board interpret phrases like "practical size" can lead to armed combat and pitched battles. :wink:

Also, the manuals, do you have the electronic sources (MS Word docs, or the like) or are you scanning them in?
