[citation][nom]treetopboy[/nom]Neoverdugo, you are probably right. The Ultrabooks Intel envisions are fully capable road warrior PCs that can do anything your desktop can do PLUS the mobility of a tablet with long bettery lives and touch capability. That is not a cheap system.Sub $500 systems are probably traditional netbook type machines with ATOM, C-50, ARM type systems with little hardware that are very specific in functionality. Still much more functional than tablet, but not overly useful for large scale business.[/citation]
If you don't mind going a little thicker, there are $300 or so laptops with fairly good performance, especially the A6 Llano ones. It's not having mobile performance that's the problem, it's having it in such a thin form factor. Cheap notebooks don't need to have crap Atoms, C-50s, ARMs, etc, the ultrabooks are just too thin to use the cheaper notebook components.
For example, it wasn't until a month or two ago that high performance CPU coolers came out for ultrabook form factors that were cheap to make when a company developed a thinner, high efficiency heat pipe technology.
