If you actually read the article you linked, you could find out that it's custom made hardware made from components which may be used in a wi-fi device, that's not the same as off-the-shelf.
FTFA:

Off-the-shelf stuff can't do this, but with components similar to that you can.

Let's work the numbers:

The screen is 13.3 WXGA, and the size is about 286mm x 179mm, and the panels appear to be the same size, and I can spot three.
Assuming a solar radiation of 1300 W per sqare meter and 15% solar panel efficiency, we arrive at a guesstimate of:
286mm * 179mm * 3 panels * 1300 W / square meter * 15% efficiency 30 W.

Looking at their website, it has a Intel Atom D2500 cpu which has a stated max TDP of 10 W, the hard drive could use 2-4 W (guesstimate), and the backlight could use from 1 to 10 watt (guesstimate), leaving still some power to charge the battery.

Now, back to the battery, assuming we get 90% efficiency when charging at 30W at 2 hours gives 54Wh.

Now, using this guesstimate of 13-24W should give from 4 to 9 hours use assuming the CPU is working at max TDP all the time.

To summarize, 2 hours solar charge in ideal conditions and (generously) assuming high quality solar cells (and a lot of other things) could give from 4 to 9 hours laptop use, possibly more.

Got any spoilers for the C++?

Entertaining, but 7 * log10 ( 64gb / 64kb ) + 10 = 52.144199393. I'm 27.
I got a C64 when I was young, and by then it was already old, and i just got a new 64GB machine :)
Judging from the replies you got, it seems only the outliers are replying to your post.

Same here except i have 64GB RAM now, so 1048576 times as much.

Disappointed about powers of 10 units in the poll :(

I have a touch screen laptop which appears like a normal laptop, so people don't know it's touch at first glance, and I usually forget to warn them. This leads to mildly annoying situations when I'm using it with someone. Someone: Hey, what's this? (touches screen) Hey, what happened? Me: You clicked on it. Now I either have to just click back in the browser, or rectify whatever they clicked on. Of course my screen is smudgy, but it seems a lot of people instinctively want to touch screens, so they are going to be smudgy anyways.

stick the drive into a linux box and:
dd if=/dev/urandom of=/dev/sdb bs=512
(obviously, make sure the drive in question is listed as /dev/sdb before proceeding)

Around three months ago i found myself in a job that i hated - I spent 5 out of 10 weeks on the other side of the world, the pay was good, but not good enough to justify the frustration the job involved. I decided to leave, and my new job paid roughly ~30% less than my old one, and ever since i started i haven't regretted it for a second. In fact, i am currently on the clock, sitting in my couch at home, while my toddler son is playing with a SATA cable that belongs to him. I voted 50% pay increase, as that's what's closest to the 100% pay increase it'd cost my old employer for me to go back to them.

I have an iPhone, you insensitive clod!
