Had a couple commuting thoughts...
For one, I got a much better route that sends me around instead of through downtown Lexington to reach my secondary work location. I wrote about my poor route choices and white knuckle experience a couple weeks ago. So a local reader of this here blog sent me a great map that led me through more residential streets and bike lanes. Thanks, Brian!
I pedaled home with this little guy in my pannier and it was noticeable lighter than my MacBook. It'll do most of what we use computers for, but not everything. But for the price, it'd be worth it to have only as your "take-home" computer. I have to take my laptop home every night... and I can feel it back there. This thing barely changes the load. And there's something to say about a low-cost option when you're pedaling through sleet and rain. If something did happen to it, you could replace it with little investment. I thought it was a noteworthy piece of commuting gear.
Get out there.
