Good news! I just got my new aluminum MacBook this week and I have been using it for Internet applications (email, web, etc.).
The specs: 2.4 GHz Intel Core 2 Duo processor, 2 GB RAM, 250 GB hard drive, Nvidia integrated graphics chipset.
So far, it has been a pleasure to use. The keyboard is a bit different from what I am used to but I have eventually gotten the hang of it. Basically, the keyboard is similar to the previous MacBook’s keyboard: calculator-type keys. Typing is okay as there is good tactile feedback from the keyboard keys.
The LED backlit display is quite bright that it drowns out any reflections on the glass. I have gotten used to it immediately. The auto-brightness feature of the MacBook seems to work but can be annoying at times — while moving the laptop, the brightness changes with respect to ambient lighting. I have turned off this feature.
Overall, I am very satisfied with this laptop. I do hope it does last a long time like my current Mac mini. I’m hoping this is a reliable product.
