Dissapointing Battery Life in MBA vs Macbook Alu

[jfriedman8]

Is it just me, or is anyone else perplexed about why the MBA, the supposed mac ultraportable, has the worst battery life out of anything that was refreshed yesterday? It has 30 mins less of battery life accd to Apple and then it does not have a removable battery. I think after today I would prefer the MBA to MB, if it were not for the battery life. Other than processor, and ports which I rarely use anyway (aside from USB) they're the same computer. I would like to see a MBA remodel with the new screen, but first and foremost I would like a 7-9 hour (at least spec'd by Apple) battery. The thing is thin for a reason, so why cant it run longer? It's not like the tech isnt out there. The Vaio TT offers up to 12 hours with the hi capacity battery. Hopefully in January we will see some drastic improvement there.
