    Congrats on the Mac Mark. I bought my wife an iMac a couple of months ago. I love it. Great piece of hardware and I really like OSx. I want to get a MacBook Pro but am having a hard time justifying the price. May just load Ubuntu on my current laptop. It currently has Vista and it is a horrible OS.

    I also use IrfanView. It is a great tool for images.

    The hardware is great, and it is basically like Linux without having to troubleshoot hardware issues.

    I would definitely recommend trying Ubuntu on the laptop. Linux is great.

    I will keep you updated on my conversion to the Mac world.
