Been using my CF-54 for a couple of months now and it's one of the best Linux enabled laptops I've ever used. I've been doing some travels lately and there are few features for this Laptop which I'd like to share.
First, I've been using extra battery on expansion bay.
It adds 32 Wh capacity to my standard inbuilt battery (41 Wh). So my CF-54 is now equipped with 73 Wh battery capacity. This gives me room to use this laptop for a full day just on batteries. I even survived a days with standard 41 Wh battery and this extra gives me almost double more.
Another nice feature which makes this thing really unique is removable HD with case. When ever I am forced to leave my laptop in Hotel room or other unmonitored location, I am able to take HD with me. Leave no valuables behind they say.
So, best Linux laptop so far.
