About that open mini card slot inside the laptop, it's for an optional cellular modem, to access internet in the field.

For example The Sierra Wireless AirPrime EM7565 LTE-Advanced Pro Module

Seriously, it's a 15 dollar dongle, who cares if the Ethernet wasn't built in. I just bought the Lenovo Docking Station for my desk anyway, which is the only place I would use the Ethernet port. I think some of you will never be happy regardless. More the Ethernet I would have liked to see the display bezel shrunk down in size and dedicated GPU used for the 12.5", the 14" is actually almost the same dimensions as the 12.5 because of that huge bezel so there was plenty of room internally for the GPU.

Would it make sense to expect the fans to kick in more on the Yoga if it sported one of the i7 processors?

By whatever passes for logic in my considerations, I expect the slower i5 processors to run cooler than the faster i7 processors.

Am I mistaken? that is, does the 15W rating on all four processors essentially mean that they will all run at the same temperature when under load on the same job?

Thank-you for your super-comprehensive and detailed review!

Be aware of the TPY display's PWM, it's killing my eyes .. i want to sell it at this point because of that.

You carry out 'real world' tests for battery life, how about doing the same for weight (specifically on ultrabooks) e.g. the weight of the laptop+weight of the power supply+any extra adapters needed for connecting typical devices e.g. ethernet, external monitor etc..  - would be a better gauge of what a laptop will actually be like to carry around all day for those that want an ultrabook because they are on the road all the time

There are serious ghosting and screen image retention issues with Thinkpad Yoga. Don't Buy! Until Lenovo acknowledges the problem!

There is a thread about the issue hosted on the Lenovo Edge forum. Lenovo ignores it.

love that you checked dpc latency, but isn't that test app not compatible with windows 8? latencymon however will report dpc latencies accurately in win 8.

i would be incredibly grateful if you could retest this.

What's the big deal about the missing ethernet port? I just bought a usb hub with integrated RJ45, for sitting with the Yoga at my office desk (don't have the OneLink PRO dock yet).

What I don't understand why the developers chose such a flimsy Mini-HDMI (even worser the MICRO-HDMI at the Yoga2Pro). I'm sure a full size HDMI would have fit as well, like at the VAIO flip 13A.
Once I touch lightly by accident the HDMI cable the connection is down. Thats nothing I can work with. :-/

Would be one of the best rated machines on the entire site if it were not for that idiotic decision not not to include an Ethernet port (thank you Notebook check for considering this). This stupid fashion fad of leaving off Ethernet needs to stop. Samsung has shown that Ethernet ports can be made to fit in very slim machines,  so there really is no excuse.

If Lenovo were also to make one of these with a larger screen and better colour accuracy my money would be theirs. Love the inclusion of a digitiser and it really should be a standard feature on these hybrid devices.

Since the Yoga has a 2,5" SSD and in some regions just a regular HDD + small caching SSD, does this mean there is a free mSATA slot? I'm really curious about this. It would give the Yoga an edge over other ultrabooks, because you'd be able to fit it with both a fast mSATA SSD and a large regular 2,5" HDD.

As far as I know, the slot for the small caching SSD is M.2 42mm (the M.2 standard is the successor of mSATA).
You can use a SSD like the new Intel Pro 1500 120GB

Display 76% ?!
