Off-topically I have to say that "Shachar Shemesh" totally rolls off the tongue.

Think of it as a Kindle with:
Color
Openness
WiFi instead of Cell
... and no battery life to speak of.
Little nit-pick: The guy in the vid says that the tones are interrupted to represent data. This is wrong, the tone actually switches frequency. It's called Frequency Shift Keying.
Just goes to show ya that MIT guys will crack a nut using a bulldozer. There's plenty of dedicated level-meter chips around which cost next to nothing and provide a better, logarithmic response, which is what you want for sound.
The LM3915 is an oldie but a goodie, you can even daisy-chain them.
I stopped reading at "...I don't think its to bad." (second paragraph.)
I'm sorry, but I can't possibly trust the opinion of a reviewer who can't write.
Considering that I calculated 27 years of error-free continuous writes, I decided that a bit of swapping was fine. Heck, I was more concerned by atime originally.
It's working fine. What throughput speed I lost is countered by zero random access times, so it's pretty zippy.
I've been running my home desktop/server (Linux 2.6) on a Sandisk Cruzer 8GB usb stick (root, swap, tmp, everything except large media files) for a year and four months without any glitches. I've napkin-calculated that at current usage and wear levelling, I should be able to use it for over 50 years without a failure. Funnily enough, the portable USB drive that I use to back it up failed last December. I keep multiple backups, I didn't flinch.
Then again some flash devices fail miserably and silently. I've had a few 64MB and 128MB stick batches with stuck bits, and those were practically new. The operating systems they were used on didn't detect the errors, I did, by trying to open garbled files.
My wish list: A SATA gizmo that has 4-5 USB connectors with each their own bus that presents itself to the SATA bus as a single drive, and does RAID-5 automatically. That'd be sweet.
Always draw your curves, then plot your reading.
