Fry's was always a strange beast. At it's heyday, it had a great selection of computer parts, an OK selection of electronic parts, and a non-zero selection of test equipment -- but this was more than anywhere else, I guess. Customer service was always lousy, and the store was pretty famous for putting returns back on the shelf. This was not entirely irrational because it was not uncommon for people with short-term needs to make use of the "Fry's rental plan" by which they bought something like an oscilloscope, used it for a week, and returned it. For a long time Fry's had porn out in the checkout line. You could pick up some Jolt Cola and a Hustler on your way out after getting some DRAM sticks.
It was great to have around when you needed a specific thingamajig to connect the whatsit to the doohickey, especially before the Internets, but overall, I didn't do much shopping there except in "emergencies."
One thing they did do nicely was have an efficient checkout system: one line and multiple tellers, with a dispatcher at the front of the line to send customers to the next open cashier. That was great. Of course, they were one of the first stores to have a security guard at the door to look at your receipt. Always hated that.
A fun thing about Fry's is that the stores were themed. I think the one in Palo Alto has gigantic components on the wall, so it's like you're inside a computer. The one in Campbell is Egyptian themed because why not. They also have random "exhibits" of old SV stuff, including an Apple I under glass and some interesting power tubes for radar applications.
I haven't been in a Fry's in years. I won't miss it, but I do have some nostalgia for when it was new (to me). It sort of went with a different Silicon Valley than we have today; scrappier, grimier, nerdier.
I don't live in SV anymore. Is Central Computer still going strong? That was a great place to build a system. Their prices weren't great, but they people there knew what they were doing. You could walk out of there with the parts to build a fully customized system, which was a lot of fun back when building computers was fun.
