For the last several years, I've taken a small netbook computer with me when I've been touring. The computer is an 8.9-inch Acer Aspire One with a solid state drive, not a conventional hard drive. Because the drive has no moving parts, it's been great when I've been on rough roads. And over the years, I've had a lot of good use out of this machine.

Lately, for any number of reasons, it has started to give me a little bit of trouble. A few times, the computer hasn't been able to find the drive and from what I've read, this can be a sign of much worse problems to come. Because of this, I'm now starting to look around for a replacement.

What do you recommend for a computer you can take with you on a tour?
