My recommendation would simply be to purchase an Apple computer - if you're in the market for a new laptop. Using iLife software, you can easily create professional looking slideshows and burn them to CD or DVD. It's not a service you'll pay for after the investment of the laptop. Plus, MacBooks now run Windows if you are attached to Windows (and it's viruses) for some reason. It's a great way to make slideshows and easily create a file to post to your website!
