So far I have found 3 free dictionaries for the Pocket PC.
i. PocketDict - the word database is supposed to be old - but this
is what works best for me. This has word completion that I really
like as I am a real bad speller.
2. WordNetCE - Seems to be the most comprehensive - but did not work
for me as it did not have word completion and was slow to load.
3. There is also a word list available with the MS ebook Reader. I was
not able to get this to work well on my x50v.
The first two you can find on
www.freewareppc.com under educational/language. The MS ebook one you should be able to find
on the MS site somewhere !
I would say try em all and let us know what works for you.
