One thing that has been nice is that Boise Airport and Denver International Airport now have free wifi, so I can check my email, blog a little (as you can see from the previous posting), and get a little bit of work done.
One frustration that I had forgotten from my last trip with my notebook is that I can't easily use Thunderbird to send email. If my memory is correct, the free wifi services block SMTP port access to prevent spammers from misusing the service. This means that I can only easily send emails from the webmail interface at my ISP. That's okay, but not as nice as just hitting reply.
I see that there are services out there with names like smtp.com that, at first glance, provide a way around this problem--for a price. If I traveled a lot, this might make some sense. For the amount that I travel, it doesn't.
