Tempted, but as mine's only 9 months old, I'm a bit reluctant to splash out... again! The main selling points for me would be proper USB ports and the proper keyboard. My origami one is pant. Keys keep jamming, space bar is nearly worn out, track pad is hit and miss, no mouse buttons, and it's floppy. If you want to use it one your lap, it take up about twice the expected amount of room, and you can't sit it centrally, else the fold falls between your legs.
But enough origami bashing!
It's a real shame the new keyboard isn't backward compatible, and that they've not upgraded the RAM or resolution to future proof it a little.
I'm mainly holding out for a trade-in offer, as there was on the Linx 10 originally (£50 at some places). I would add that Windows 10 is much more PC friendly than 8.1 (though I got round this my installing a start-menu patch).
