Much slower in what ??? browsing ??? mailing ??? playing movies/youtube ?? writing on word ?? facebook ?? those are the everyday tasks users do, a quad core ARM with SSD and Android 4/Win 8 will be perfect for those tasks with all the plus i said earlier.
There are users that do need higher performance but IMO the majority of the users that will buy an Ultrabook they jdont.
Dont get me wrong, if you need the higher performance with high battery life and you do travel a lot and you need a slim, lightweight fast Laptop then Ultrabooks are for you, but those users are the minority
You're right....most users don't need an ultrabook other than wanting a thin, fast performing, lightweight computer.
And that sort of leaves out tablets.
As an example, I bought my father-in-law an Asus tablet for him to use while he was in the hospital. Figured the small form factor, light weight, etc., would be more appropriate for him than his old C2D-based IBM T61 Thinkpad.
He gave it a couple of days of use until he almost begged to have his heavy, clumsy, oversized laptop brought in and left the tablet sit on his bedside table, unused.
So, I took it. Wanted to use it to replace my Lenovo T420 laptop for occasional light duty use. After a week, I put it down. Horrible interface.....lousy typing experience, web sites that didn't respond well to touch, got tired of losing half the screen to a "keyboard" interface when I just wanted to type in a password, was SLOW!!!, etc., etc.
Sure, it was good for watching videos streaming or glancing at email, and I'm sure it is a vast step up from doing the same on a phone...about the only competition the tablet wins against in comparison....but as a computer, it sucks!
Went back to my T420, gave the tablet to the wife. She won't use it, either. Too clumsy an interface, too slow, hates the keyboard interface.
So, tablets do have a place as a phone replacement and pure consumption device. As a computer replacement....not even close.
