if I had a 'notebook' I'd probably run both......it doesn't cost much for an 802.11b/g adapter and is great for home access also.......and some notebooks have the adapter already installed
being up here in the NW and not running 48 anymore I'm not sure how well Verizon's networks will be on my runs......but I'm also a ham and would enjoy linking via repeaters for many different things where regular technology doesn't always work...along with the many options available
