Google Chromebooks (those low-cost cloud notebooks that run ChromeOS) continue to take small steps forward. We've spotted four examples of Chromebook progress in recent days. But are Chromebooks really starting to catch on?

First, let's  look at the anecdotal progress:

  1. TigerDirect.com recently began selling Chromebooks from Acer and Samsung, joining Amazon.com and BestBuy.com as online Chromebook resellers.

  2. Google has launched a Chrome extension that supports remote access -- somewhat similar to Citrix's GoToMyPC, notes Wired.

  3. SADA Systems is now promoting web-enabled Windows apps for Chromebooks.

  4. And Google itself is promoting Chromebooks in a retail store in London.
