Chromebook is for everyone. For the casual, it's great web portals. For techies, it's perfect platform to run Linux. You get open source BIOS and laptop with slick form factor, SSD, and amazing battery life at super low price. To get that on Windows or OS X, you have to pay a high premium.
I strongly disagree Chromebooks don't make viable computers. Chromebooks make excellent computers. Computers and devices like the Chromebook and Chromebox are the future. How you use it is up to you.
BTW, Woot is selling the refurb HP 14" Chromebook for $220 plus $5 shipping today.
Woot HP 14" Chromebook
I just ordered one even though I don't really need a laptop. I might play around with Crouton and various Linux. It has the Haswell Celeron, 4 gb ram, 32 gb SSD, and 4G HSPA+. You get 2 years of 200mb month free 4G internet service from T-Mobile. The 4gb ram, 32 gb SSD, and the 4G internet was what interested me in this laptop. And I prefer 14" to 11" screen. Costco is selling the same laptop although brand new for $380. So $220 for refurb is pretty good price IMO.
