Google Chrome OS Notebook (CR-48): Discovering Developer Mode

After being surprised and delighted to receive a Google Chrome OS Notebook (CR-48) a few days ago, I’ve been blogging about my CR-48 initial observations and day-to-day experience.

Yesterday, I decided to try out Developer mode after reading an article on It’s an easy process, essentially flipping a switch located in the battery compartment, rebooting and a few other steps (outlined by here). When I first rebooted, I was greeted by an unnerving screen that declared the OS unverified. Clicking on this screen took me to screen explaining how to re-load the OS (the provided url mentioned loading the OS onto a thumb drive and re-installing). OOPS!

All I needed to do was to remain on the initial boot-up screen following reboot. By waiting at that screen several seconds, the system beeps a few times and then boots into the user log-in screen (as expected). Whew!

My understanding is that developer mode enables:

  • Shell access & other geeky fun: As I kick around in the CR-48, I may want to delve more deeply — developer mode enables this exploration
  • More frequent OS updates: The “normal” (non-developer) mode provides a beta experience. As soon as I rebooted into developer mode, a new OS update was downloaded — perhaps an OS version closer to alpha than beta?

So far, the Developer OS version seems slightly faster than the beta. The OS still struggles with pages containing Flash plug-ins and chugs a bit when trying to load several bookmarks at a time. But hey, it’s beta (or perhaps even alpha), right? Bugs and rough edges are to be expected…. just part of the experience.

I’m still surprised that I haven’t needed to revert to using my Vaio (aside from a short time on Friday). I’m finding the Chrome OS user experience enlightening in just how much I live on the web.

I haven’t yet used the built-in Verizon 3G connectivity, and may try this out today away from home. I love that 100MB is provided free monthly, but a little concerned about how quickly I could burn through that. Luckily, Verizon has included an unlimited day pass for $9.99 in their CR-48 data plan offerings.

I’ll continue to blog on my CR-48 observations — leave a comment if you have any questions.

  1. Hi Karen,

    maybe in a couple of days – but I’d like to know a bit about your favourite ‘Apps’. What are you using for music? Is there a good Notepad or Code Development Environment – like Textedit? My biggest question is does the Chrome Web App store make more sense now that you see it integrated into a notebook / OS? I know we both found the concept a little confusing talking on Twitter the other day.


  2. Thanks, Jonathan, for your comment!

    I’ve been using the Pandora extension for streaming music. I have their annual subscription, so it works out well for me.

    I haven’t needed a notepad or code dev app but I think there are some — I found this one in the store (NeoeEdit):

    From what I’m seeing, the benefit of some web apps is the ability to navigate by just using the arrow keys. For others, I think the web app provides a slightly richer experience than the web page. I’m still torn as to how much value the web apps add, and it’s one of the things I want to further research (by downloading /trying more web apps) while using the CR-48.
