Energy, Heat, And Battery Life
When you spend all day talking about high-end hardware, you're bound to hear from folks who feel strongly about the gratuitous power consumption of those components. Dell's XPS One 2710 is mostly made up of desktop-oriented parts, which benefit it in the performance metrics. However, the same potent pieces of gear also use quite a bit more power.
The same power-saving low-voltage parts in Lenovo's IdeaCentre Horizon that hold back our benchmark results effectively minimize consumption, to the point that its integrated battery is actually useful. Not surprisingly, then, Dell's XPS hits a peak power number twice as high as Lenovo's all-in-one.
The IdeaCentre Horizon also runs cooler in spite of its ultra-thin dimensions. Significantly less power consumption translates to less heat to dissipate.
Unlike Dell’s XPS One 2710, which only looks a little like a tablet, Lenovo’s IdeaCentre Horizon is portable and has a battery. Because this configuration is a first in my lab, the Lenovo stands alone in this test. For a bit of perspective, its combination of large screen and small CPU/GPU barely outlasts the opposite combination.

Would be nice if they have truth or dare.Reply
This explains the "for those who do" partReply
My only question is why not Haswell?? with all it's benefits for mobility where are the portable with the processor...Reply
As reported on Slashdot IT - "defence agencies of key Western governments such as Australia, the US, Britain, Canada and New Zealand have banned Lenovo gear from being used in sensitive areas, because of concerns that the Chinese vendor has been leaving back doors in its devices for the Chinese Government."Reply
I wish Tom's would aim their incredible testing abilities at these types of claims. I would like to know if MY Lenova is making me vulnerable.
You're right, if we treat this as a huge tablet or an IPC, it looks pretty good. Thanks!11250051 said:Try using this for any length of time as a table pc and your neck and back will be in knots.

I'm a help desk technician and I'll tell you one thing that I've learned about mobile graphics cards in all-in-one PCs; they are a very bad idea. Just yesterday I had the pleasure of troubleshooting a 4-5 year old Dell all-in-one, which had a problem with the video going black for thirty seconds at a time. I of course attempted to upgrade the video drivers, and found out that neither Dell nor nVidia had ever updated the drivers. I believe the computer originally shipped with Vista 32 bit but was advertised as being Windows 7 upgradeable. I base this opinion on the reviews that I read about the machine, and also on the fact that it had both a Windows Vista and Windows 7 logo sticker on it. Dell's site didn't have any drivers newer than 2009 and nVidia's own auto video driver detection application couldn't identify the video card. In conclusion, I think using a mobile video card in a like this size is lame. But I do applaud Lenovo for trying out new ideas. I would have more faith in the form factor if a company like Samsung was behind it. Also, I should mention that I'm typing this very review on my Lenovo X230.Reply

Retired; and need big screen to see ; would take it on car travel but airline travel?Reply

It's about as long and wide as an oversized carry-on bag. Which means you may get it past the gate, or not, depending on how strict the airline staff is being at that gate. And you'd want something to protect the screen.11285869 said:Retired; and need big screen to see ; would take it on car travel but airline travel?
