I played with a few of the new Apple Intel base systems last week. Wow, definitely faster. Of course they will have issues, but I am sure Apple will get them worked out. Needless to say, I think Intel was a good move.
This is an interesting approach to writing tech books. We have purchased several electronic copies of technology books at work recently. Of course, a hard copy is also nice to have.
We recently purchased a Canon SD600. The Canon ELPH series usually has good reviews (although I didn’t find many reviews for the SD600). This one had a couple of new features (compared to the SD450) which include Widescreen mode (16:9) and ISO 800 for shooting indoors with no flash (as I understand it). I am sure you will see pictures from it in the future.
