Yeah, personal opinion is if you plan on using a laptop just for GPS, then just buy the standalone version. My buddy has the Rand McNally and he loves it. Of course after the little fiasco he started on some random review page. He went by the "easterbunny" and apparently got everyone on the other trucker forums panties in a wad. Rand McNally got a hold of all this controversy and immediately contacted him and worked up some updates to fix their image in front of the truckers. All is well now. Just update it and it'll be terrific.
I use my Acer laptop for GPS, TriPak scanning, trip information, financial info and all that important crap. So it's a major tool in my cab instead of a waste of laptop.
