Ars reviews the Macbook Air

Ars Technica has an in depth review of the new laptop from Apple, one definitely worth a look.

They state various problems, from the very slow 1.8" hard drive to the erroneous claims about battery capacity.
While Apple claims that the laptop can work for four and a half hours on a full charge, the reviewer only was able to squeeze two and a half out of it. This is unforgivable in a laptop of this price and type. Apple should think of addressing the problem soon since you can't carry a spare battery with you either.

The charging time is of five hours, according to the reviewer. That's probably due to the small wattage of the AC adapter. Nothing that can be easily be fixed by buying a better one, since the MagSafe connector placement is a bit non-standard.

The RAM is soldered onboard, but that is a compromise that had to be made for it to have this kind of thickness.
There's definitely some room, even need, for improvement.
