I got the netters flash cards for my pocket pc (its like a palm pilot thing). You can search on google or anything like that and find them. The program is 50 bucks (not E.C. lol)
I like them. It sure beats walkin around with the cards. They are exactly the same as the cards except they have a little more descriptions on most of them.
For 50 bucks, its a little much but i think that its worth it.
