On the dictionary issue, there seems to be a difference between K3 and earlier, on the one hand and K4 and Touch on the other. On K3 and earlier you can purchase a compatible dictionary (e.g., Merriam Webster Spanish-English) and then set it as your primary (see Kindle Support-->Kindle Keyboard-->Customize Your Reading-->Choosing Your Primary Dictionary). K4and Touch, by contrast, include access to several dictionaries out of the box--one for each of several languages--but limit your ability to change primary dictionary to those preselected dictionaries (see Kindle Support-->Kindle-->Customize Your Reading-->Changing Your Primary Dictionary). Unfortunately, the preselected dictionaries, though good ones for the respective languages, are not translation dictionaries (eg, no Spanish-English, only Spanish-Spanish). I've emailed Amazon to confirm this--awaiting a reply. I can probably deal with using a Spanish-Spanish dictionary and I appreciate having such a good one (the Academia Real) available with the price of the e-reader, but there is a little less optionality.
