anyone have experience with these products. the 700 is the deluxe, plug and go. the 300 has smaller storage, so i have to plug, download, then i can go. but i can only download as much as the size of the card, but i don't mind buying another card. but then again my mom only goes from socal to vegas. so which one should i get her. if anyone has experience with these products, please let me know what's up.

thanks.
