You can get program (actually ther are a few of them - different ones can do different/more things) to perform e-book reading .. PC or PDA .. don't know about 'smart phones' .. That way you have a more versitile device rather than a one function 'sony e-book reader' ?
? May be this should be under 'equipment' rather than 'communications' .. a book can communicate to you .. but how do you talk back? Effectivly that is
