Of course ASUS would win such a contest :P Is a netbook vs tabled as Bear very good pointed

If you want to make this even, compare a ASUS tablet with the iPAD (look for EEE Slate series).
Anyways, if you intend to buy one of these, I strongly suggest the iPad. Don't know about the others, but I hate netbooks, they're like laptops who s*ck big time. Want a Windows 7 with Aero? Pretty good performance. Want a HD movie? Well...it turns out to be a slideshow of frames. Want an SQL Server on it? System halt!
My point is, iPad are really cutting edge technology, of course with lot of advantages and disadvantages (see the 0.5 m cable and the need to charge it every day or often) and from what I've handled some by now, I would buy one ...but netbooks? Nah. I don't think those few hundred grams in minus with respect to laptop worth when the lack of performance is so big.
Also ....Apple is Apple
