Keychron Q11 for $250: While this is a perfectly functional split keyboard, I find it hard to justify the price. Primarily, the typing experience is incredibly underwhelming, feeling and sounding thin and hollow. The typing angle of this keyboard feels fairly shallow, with no way to adjust it, and even partial wireless support (with one half connecting wirelessly and the other connecting to the “main” half) is absent—something that has come to be standard on the majority of Keychron’s offerings. This isn’t a bad keyboard, but at this price it doesn’t feel on par with Keychron’s non-split offerings. Ignoring the price, this keyboard is lacking in both practical and ergonomic features.

At IBEW Local 26 near Washington, D.C., which sits at the heart of the data center capital of the world—northern Virginia—membership has doubled since 2018 to more than 14,700 electricians. Apprentices start at roughly $26 an hour. By the time they complete their training, journeyman electricians earn about $59.50 an hour—more than $120,000 a year—plus benefits that often include health insurance and a pension. Add in overtime hours, or being a foreman, and electricians can make closer to $200,000 a year.
