Good backlit English and English-Spanish dictionary

I actually got this as an on-the-go backup for my main Sharp PW-E550 English electronic dictionary. I'm not using the Spanish-English part of this gadget so can't comment on that part. There are about 90,000 English entries (and another 60,000 Spanish ones). An entry is a word, a phrase, a person's or geographic name, etc. Let's put this way, it has most of the commonly used (English) words. The vocabulary is "PG-13" if you know what I mean, so don't look for vulgar slangs here.

There are basically three dictionaries here:

1. English dictionary and Thesauras (Oxford American Pocket version)
2. English-Spanish
3. Spanish-English

Two salient features of this dictionary are: 1) the keyboard is very comfortable to use (but the layout takes getting used to), and 2) it has backlight, which is fabulous. I love this dictionary. I still need my PW-E550 when I read serious books because that one's got twice as many words and definitions. But for everyday use, e.g., when you read newspapers or just want to have fun with words, this is a good companion. Did I mention it has (green) backlight at the touch of a button?

The dictionary uses one AAA battery. If you don't use backlight, the one battery should last a long time. (I know this because my PW-E550 is very power-efficient.) If you use backlight a lot, obviously you should carry a spare AAA with you.

If you have kids, this is good for up to grade 10 or 11, I believe. After that, a kid needs the bigger-lexicon PW-E550, depending on the quality of your school district, of course.
