I've been looking for a decent laptop that can run OpenBSD (recent Chromebooks are nice in terms of battery life, but suck at hardware support from anything but ChromeOS). I trawled the OpenBSD mailing list archives a bit, and found that the Lenovo ThinkPad X201 is supposed to be very reliable and well-supported, as well as being fairly small and light. It's a bit old, so it's not exceptionally lightweight by modern standards, but I can live with that.
I found and bought
an X201 on eBay for $300. Bargain, considering the reputation this laptop has for reliability on the 'net. I can't wait to get my hands on it and install OpenBSD.
Meanwhile, my
recent PC Case Gear order has been delayed by a lack of the SATA cables I ordered. This turns out to be a blessing in disguise, as I can now request an additional SSD to be added to the order for my new laptop, to replace its HDD.
At the moment, I'm mostly considering an
Intel 530 Series 120 GB model. I won't use more than 120 GB on a laptop, and the X201 is old enough that it doesn't support SATA 3, so capacity and performance aren't worthy considerations. On the other hand, that Intel SSD has very lower power consumption (fuck yeah battery life), as well as a 5-year warranty (I care more about drives failing in laptops than in desktops, because I might be travelling with no access to backups when it happens).
I'll think about it some more and add an SSD to that order later today or tomorrow. Meanwhile, feel free to post suggestions.
