I have to say, I really like the using the trackpad on the Air, especially the hand gestures for navigating web pages and such. However, I will be going out of town for two weeks and it will be first time that I‘ll to do all my typing on the Air instead of my desktop computer. On my desktop, I primarily use the mouse. I‘m not much into keyboard shortcuts. QuicKeys 4.0 enables me to activate menus and keyboard shortcuts, so I don't have to remember all the shortcuts. (In fact, I have two QuicKeys shortcuts that enable me to quickly select the last letter or word I typed without using the Delete key. It’s not perfect, but it beats having to raise my fingers to reach the Delete key every time I make typing error.) So I‘m wondering if I should splurge for a wireless mouse of the Air? Something tells I might need one in order to get writing and other things done quicker. Or should I just learn to use the trackpad because it’s better than the mouse? How many of you use a mouse with your Air? Or do you mainly stay with the trackpad? BTW, my use of the mouse on my desktop is not limited to just typing. I use it a lot to navigate applications, make selective screen shots, and drag stuff from app or Finder to another.
