I seem to be getting especially slow boot times and short battery life on my new MBA13 (2011).

Boot time (From power on to desktop): ~18 to 20 seconds (Room mates older 2010 MBA13 boots in 12-14 seconds to desktop on SL, so different OS and different hardware, but both older)

Battery Life is about 5 hours (50% brightness, keyboard backlight turned off, no apps running except browser and constant multi tab browsing), basically replicating Apple's battery rundown test that they use to come up with the battery figures.

Sadly that is nowhere close to the 7 hours stated on their website or the 8-10 hours we can get out of room mates 2010 MBA13 running SL using identical workloads!

What are you guys getting and what should I realistically expect?
