Nobody carries a laptop around 24/7.
When your home at work, ergomonically a PC is much better to use. If you used a laptop 24/7 then you would notice the difference hugely. My cousin used to only use laptop for 6 years straight, spending £2000-£1500 on his laptops. He finally bought a i7 PC and now all he ever needs is his 11" netbook for day to day work. I mean I would say 90% of buyers of this ultra book couldn't use the full processing power of a i7 chip, and especially not the performance claims of this full i7*.
It seems like the laptop is trying to meet the tablet PC's portability, and the tablet PC is trying to meet the PC performance. People just need to man up, and realise that if you want a true multimedia laptop experience, your going to have carry than extra pound in weight for the sockets you need, USB and multimedia and a dvd writer. For the day to day laptop needs of a "ultra book" user, I don't believe you need anything more than a Quad Core 2, as what exactly will you use this ultra book for especially?
This isn't a $400 laptop, and the prices of this laptop haven't even been realeased yet so it can't compete with anything yet. The biggest bottle knecks in todays PC's and laptops isn't the processor or the graphics cards - ITS THE HARD DRIVE.
This chip will run a laptop just as slow as a 6 yr old PC if the HD is clogged up and badly maintained, and to really see the speed that'll be advertised from this Ultra book, you'll need to have a SSD drive inside.
