Baristas are awesome and super friendly. Get an Ernest loyalty card for free lattes. If you stay late, they'll give you free refills on hibiscus tea. They brew Stumptown and it's awesome. Stay late enough and you can order some bomb beers and head back to the Tiki bar. The partially-covered patio has misters for those extra hot desert days.
Plenty of outlets available; there are three for the front window bar seats, another two near the merchandise display, and three large power strips for those using the bench seats across from the register.
