The problem with netbooks are battery life (much improved with 6-cell batteries, but at the cost of more weight) and the screen aspect ratio (not tall enough). The 2nd problem goes away if you can use it in "portrait" mode, which is possible with a convertable netbook. These are new, and the only one available currently is the
Classmate PC "tablet". Asus is supposed to be introducing the
Eee PC T91 and 101H convertible touch netbooks this spring. However, there have also been news reports that Asus is delaying the introduction of new products, perhaps including these.
