MacBook Battery Life (for writers)
I promised to add a little bit about the new MacBook's battery life. Well: If you're a writer, you're going to love the MacBook. Get the cheapest one and fill it with RAM. With the brightness of the screen on the lowest readable setting, I get 5 hours and 50 minutes of writing in my favourite café. Of course, I have WiFi and Bluetooth turned off then, because I want to actually _type_ this long. It works. And after almost 6 hours, you certainly need a pause.
If you turn WiFi and/or Bluetooth on and do more than just typing in TextEdit, battery life will soon degrade to 3-4 hours. Still good, but certainly not the same. I'm very, very content with my MacBook's battery life, I have to say.
