You don't want to neglect broadband and you can easily offer 3D product view, animations and movies as an option with a simple file size in k warning. That may sound strange, but most people despise being categorized or identified by an order number. While that is how you should be organizing your marketing data, you want to always think of ways to personalize and humanize your content. Get yourselves a spokesperson or make one up. Wendy's Dave is a good example, but Colonel Sanders is easily identifiable as well.
People like to deal with people.
Get someone to proofread as well. Selling allows you to do things like using Title in descriptions or ALL CAPS for special emphasis. However, some people on this earth know how to spell and they look down on folks who don't. You want them focusing on what you say, not the errors. Make the extra effort to get it right and make it easy to read.
