[synatribe]

okay, so my dad is planning to buy another laptop but he needs wireless internet EVERYWHERE, even if hes like in the middle of a field in Georgia,
he also needs a computer with a lot of GB because we are planning to use that computer to download korean dramas, Im planning to just get an external harddrivve but that computers going to be mostly at his workplace, so I wont be able to transfer all the files onto the external harddrive unless I go to his workplace [which I will never do] anyone have any good suggestions? we were looking into Hp dv9700t oo yea and he dosent want to spend more than $1,500, but his main concern in having wireless internet EVERYWHERE,
isnt there like a card or something to do that? anyways could I get some suggestions :]]]]]]
