If you are one of those persons who define "techie" as someone who is an "early adapter" or someone who has the dough to keep up to date with the latest gadgets being put out by manufacturers and vendors , then think again :
A laptop is a penetration tester's most important arsenal much like the M-16 for the U.S Army. However, new laptops on the market nowadays come with an "Express Card" as a replacement to the old reliable PC card or PCMCIA slot. This is BAD news if you want to learn wireless security testing techniques. All current and previously available Wifi, GSM, GPRS, 3G,etc. cards requires the PCMCIA slot and as of now there is none yet available in Express Card form. Now unless you are willing to settle for pre-owned units, go to your nearest dealer and get one with a pcmcia slot while there are just a handful left such as those from MSI VR series.
