Over the weekend, I took my MacBook out for some time at Borders. I had to do work on the laptop that I cannot do on the iPad at this time.
And this is an older MacBook. Late 2008 and the battery life has been put through it's paces in the last couple of years. According to a battery utility, it's got 80% left of the original charge left. When it gets to 70% or less, I'll probably have to decide if I should get a other battery or invest in a new MacBook.
I turned it on and it attached itself to the free wifi. And the battery indicator said there was 2.5 hours of work I could do. But I wanted to spend my afternoon there working so I turned off the wifi.
It has been quite some time since I've done that. The long battery on the iPod touch, and specifically, the iPad has really spoiled me. The battery life jumped to four hours!
I was there for about four hours and got about three hours of work done so there was some change left in the battery had I wanted to stay longer.
But my point is the wifi chip. What a power hog! I hope today's wifi chips are more battery friendly. But if they are not, someone need to invest some time and research on making wifi use more efficient and the chips draw less and less power.
We'll be using wifi for years if not decades more. Bring mobile isn't just about more efficient CPU, display, or bettery batteries. It's about other components of the mobile devices or laptops. And it's also about programming for power management.
For now, wifi chip and its ubiquity is one area that I see that can help mobile warriors work longer and worry-free.
