Asus Chromebook Flip
I recently bought a refurbished Asus Chromebook Flip C100PA (recently replaced by the C101PA - faster processor, USB-C ports and noticeably-inflated price tag), and so far I'm finding it a great little machine.
The reviews of the Flip frequently comment along the lines of "ooh, it's a bit small, isn't it" - well, I don't want to lug a paving-slab around with me, and as a previous owner of two Psions (3c and 5mx) and an Eee 701SD, I find the Flip positively spacious by comparison. I also like the performance, and the all-aluminium-apart-from-the-glass-screen construction makes it feel to me like a mini-MacBook at a quarter of the price.
Why raise this here? The Flip runs Chrome OS (the "philosophy" of which, Windows 10 S appears to share), and it packs an ARM CPU like these new machines. Granted, the Flip doesn't take a SIM card, but then the latest model costs about half of the price-tags quoted for these Snapdragon slabs.
These new machines won't suit every user - then again, neither will a Chromebook - but it's interesting to see a rise in the number of ARM-based laptops, and good to have more choice out there.
