From a quick internet search, that looks like a nice little machine. A worthy successor to the great old Eee PCs, Acer Aspire One (I think), MSI Wind and so on - those marvellous little netbooks which fell from favour for some reason.

I'd be unable to resist trying to upgrade it to Linux, of course, but I dare say W 8.1 has its merits. If you do decide to try the dual-boot approach, you might like to research installation to this machine a little carefully. I've yet to own anything that modern, but you'd need to deal with UEFI/secure boot (worry about that as and when...) All quite achievable.

You might also like to research creating recovery media for it, in case anything should go wrong, and how to recover the Windows installation key. All best done soon, before trouble strikes, whether you intend to dual-boot or not. Not a concern with Linux, of course *ahem*...

Have fun with it, though. It looks great.
