text: my husband needs to purchase a dell laptop. he is very mobile, so wireless is essential. any suggestions? he needs a good middle of the line laptop.  we are considering the dell latitude 620.  does anyone own this model?  if so, are you enjoying it?  also, how are you accessing the internet?  i am considering either a cingular or sprint wireless access plan.  any details on that as well? thanks!! the xps 600 is not a laptop. huge desktop!  i've ordered 14 laptops for my company in the last 2 months.  i would suggest either the inspiron 9400 (low end) or if necessary the latitude 810 or 620 .  the xps laptos are very expensive starts at 2500.  very good though (graphically). an inspiron is probaly the best though for the money.  latitude would probably be second on my list though.
