New MacBook Suggestions

So I have a new MacBook. It's my first and only Apple product. Any suggestions?

I'm looking for a good terminal app and a good tiling window manager (a la i3). Also, is there a way to maximize windows without making them full-screen?

Battery Life Answer?

I may have found an answer to my question. My battery life is back over 24 hours. Investigation suggested that it was syncing-related. I tried the following two things (after other failed attempts) based on the weak evidence I had:

1. Set my phone to always keep wi-fi on during sleep (under Wi-Fi, under Advanced in the menu). I have weak cellular coverage in my house, so falling back to cellular isn't necessarily better for battery.
2. Disable Currents from syncing. It is a heavy abuser, and I don't use it.

Problem solved.

By the way, two apps I have used for keeping an eye on battery are BetterBatteryStats (good for investigation) and Battery Widget? Reborn! Pro (general purpose, good for keeping an eye on drain).

Android 4.2 Battery Life?

My Galaxy Nexus' battery life has gone from about 25 hours on 4.1 to 8 hours on 4.2. The same is not true of my Nexus 7.

I haven't figured out what it could be. Any ideas?

• Go to Apps, then to All
• Find Google Services Framework
• Force Stop
• Clear Data
• Go back to Settings
• Enable Wifi

Your mileage may vary.
