Older Ultrabooks vs netbook
Last year my youngest daughter was keen on small, light and cheap device with keyboard after getting frustrated with producing schoolwork on her iPad.
I looked for a netbook and checked out Chromebooks, but in the end, an old 'Ultrabook' - a Toshiba R600 turned up on a local auction site ex-lease which I got for about £35. Hate to think how much they originally went for, but battery was still good, 12" screen (1280x800?), but small enough to go everywhere, 3gb ram, 200gb 2.5" HDD, CPU is duel core, but better than most Atoms. Was going to throw a SSD in it and maybe a light weight Linux distro, but after an update to Win 10 and keeping it clean, performs surprisingly well anyway.
Ended up keeping it for myself as traveling it has a couple of usb ports and SD slot; somehow boots faster than my i7 powered work laptop with w7 and a whole lot of services running.
So not a bad alternative to classic netbooks and can run any OS if Win 10 is not your OS of choice.
