Whenever I’m in Silicon Valley I always make a pilgrimage to Fry’s Electronics. Because no other electronics chain even comes close to the geek wonderland that is Frys.
Every store has a separate theme. This one is Mayan / Aztec. You want laptops? They’ve got about fifty models, plus every gadget, adapter, cable, and electronic doohickey anyone could want, and TVs, stereos, GPS, cell phones, etc, as well.
I bought a TP-LINK portable router for those times when there may be a wired connection but no wireless (as just happened at a cousin’s house.) It also functions as a router and repeater.
