Grrr! I still can't get my MacBook to connect to any wireless network. It doesn't seem to matter whether the WiFi network is protected or not. Tried two different routers too. Ethernet connection works just fine, it's just a pain to have to remain tethered. I know that it must be able to connect - I once saw Jeff Goldblum connect to an alien spaceship with his Mac, so an 802.11g network should be a piece of cake. But it's not. There's a lot of info on the web about troubleshooting Mac Airport issues but none of this has helped. The rig can see the SSID but just can't connect. Ahh well, one for Apple support methinks.
Other than that, things are going pretty well. I've installed a few apps on such as Firefox and ecto (blogging tool) it without any real difficulty (next week I'll talk more about this). I'm finding that I'm learning the keyboard shortcuts pretty quickly - find them easier to use than using the trackpad and buttons.
