Hi jaamsk,
Welcome to
Laptop GPS World.
Could you please wait a little bit. I just sent Semsons a quick e-mail regarding your question. My guess is that since Garmin Mobile PC is a brand new product, and Semsons just added it to their line of products they sell, they might have overlooked adding it to the discount coupon. But that's just my wild guess based on no knowledge of the facts. As soon as I receive the reply I will post here. Or better yet, Carlon, or someone else from Semsons, may post here directly, if they wish.
lforbes, I'm looking forward to hearing from users how they compare the two products, too. There is no clear winner, both products are very good in what they do.
What kind of computer are you using? Laptop, UMPC, or TabletPC? Keyboard, or touch-screen? What is your screen size? Do you need to print maps?
