Pyra, PocketC.H.I.P. — Not quite the same, but...
Petter and Elena both talk enthusiastically about the Pyra. I am currently waiting for the shipment of my C.H.I.P. kit — I pre-ordered my kit when it was still in kickstarter phase, and got the PocketC.H.I.P. level.
It is clearly not the same nor equivalent to the Pyra — The PocketC.H.I.P. is a convenient packaging for what is chiefly an System-on-a-chip; the C.H.I.P. is a small system by today's standards (single-core ARM, 512MB RAM, not meant to be expanded), but still it looks quite usable as a very portable and usable Unix system. Oh, and of course — It's also Debian by default.
I got quite interested in what the Pyra was like. However, the pricing does not make much sense to me. OK, the Pyra is quite a bigger machine, but... While the PocketC.H.I.P. costs officially US$70 (and before June, according to the site, US$50), the Pyra starts at €500 (plus taxes)... It is just too much!
Anyway, I hope to have mine in time to go to DebConf. I also hope Petter and/or Elena can make it this year. And I hope we can compare the systems. I guess the Pyra will sit closer to a regular laptop... But anyway, my two last laptops have been at the bottom of the price scale (both from the Acer Aspire One line). I bought both for around US$300, used the first one as my main laptop for over five years, and have been three with the current one, completely happy.
