I’ve used the Lenovo Yoga that has a similar hinge (but is not detachable).
One of the drawbacks to that hinge is is when you bend the screen all the way back to use it as a tablet, it leaves a gap in the back, so when you use the touchscreen, the screen actually bends a little from the pressure. I’m not sure if that will lead to problems in the long run, but it’s something I would watch out for.
On this device you can’t bend the hinge all the way back. To turn it into a clipboard, as opposed to tablet, you detach then reattach it so it covers the keyboard. At 1 and a half pounds easy to carry.Still unknown is battery life, IIRC they said 12 hours, and pricing. The base price with an i5, 128g SSD and I think 8g memory it was $1499. Most will come with an i7, bigger drive and more memory.
Available by the end of the month I think, pre order in a couple of days,
I bought a Yoga for my wife some time back. Windows 8 sucked big time.
Be very careful. I purchased a Lenovo Yoga 2 Pro a year ago. Core i7 with 8 meg ram and 500 gig SSD, The thing is light and blazingly fast! I love it.
One day I was opening the lid and I heard a TICK and all of the sudden things started jumping around on my screen like I was dancing my fingers across. The digitizer cracked from one hinge to the opposite corner. Lenovo wouldn’t cover it under warranty so finally I relented and they said $600 to repair. Then they didn’t have the part to repair it and suggested I contact their certified service partners Radio Shack, Best Buy or EBay. Yep they suggested Ebay as a service partner.
I was incredulous and said really... I am going to surf ebay to find a broken down Yoga to fix the screen on my $1400 laptop? They said yep. So eventually I found a place called 365laptoprepair.com out of California. They have the part for $349 and will install it for $50. I got them to fix it and it is like new.
I still love my Yoga but I am really careful with it and will never buy another Lenovo product...
