SSD in Air: How fast? How much energy?

[netdog]

How fast is the SSD going to be in the Air compared to the 4200RPM drive. How much of a difference will it make in booting, loading apps, and other tasks?

Also, would an SSD considerably extend the battery life?

Is it likely that Apple Service would add do a replacement for a buyer of a conventional drive with an SSD at a later date? Surely the prices of these drives will plummet soon now that they are going to be produced in greater numbers.

How fast is the SSD going to be in the Air compared to the 4200RPM drive. How much of a difference will it make in booting, loading apps, and other tasks?

I can't remember the excact specs, but SSD reading and writing times (mostly wirting times) are insanely quicker than a conventional HD, especially a 4200 RPM 1.8" drive.

Also, would an SSD considerably extend the battery life?

It would, since the laptop would have no mechanical parts that move, only using power to power the SSD.

Highly unlikely since that seems very un-Apple-ish.

Engadget had an article comparing the times of the two drives.
