"I picked up a wonderful new sub-notebook over the weekend, but this one has some history behind it which is worth explaining first.
When I bought my Acer Aspire One 522 a little over a year ago (November 2011, see original blog post here) I came very close to returning it because the screen resolution was only 1024x600. But even in the first few hours of using it, and loading Linux on it, I was so impressed with it that I decided to keep it, and I've been pleased with it ever since.
Last week I saw an Aspire One 725 on sale here, for 399 CHF (about £280), and the specifications said that it had the new AMD C-70 CPU (my AO522 has a C-60), more memory and a larger disk."
and
"The Aspire One 725 has a UEFI BIOS, with Secure Boot enabled by default.There are a couple of Acer-specific things that are important to know here. First, the boot-select option is disabled by default, you have to to into the BIOS setup (press F2 during boot) and then change that to enabled before you can boot a Live USB stick.
Second, you can only disable Secure Boot if you have set a BIOS password. Yes, I really meant that - go back and read it again if you want, I'll wait. Grrr. Who does that make sense to? What is the logic there? "
