I think it comes closer to killing the Mac Book than the iPad.
Same CPU,
Not the same. The $999 model has only a 1.4GHz/1.6GHz underclocked CPU with 1/2 the L3 cache and only a 800MHz memory bus. You are taking a performance hit if go with that model.
The new 13" versions are $100's more in price.
For that you get 5 hours of battery life, plus the instant on and 30 day standby time.
Stanby time???? You buy it not to use it?
The MB has 10 hrs of battery life so it is double the amount of time.
Sounds like a Mac Book killer to me.
Not even. For folks who only wanted limited performance and minimal weight coupled with minimal price .... the new MBA 11" will siphon those folks away.
However, if need to be mobile and working for an 8 hr day.... the new models have problems. They can't go a whole day. Likewise if wanted to use some apps that need some horsepower. There is going to be a difference.
MB sales will drop a bit, but they won't crater. This will make the MBA look like it doing something reasonable in the market since its sales will finally jump higher than the Mac Pro.
