There are some things that it is convient to have a desktop icon for, such as a web browser. Adobe reader is not. I have never ever seen anyone open adobe reader than search for a PDF. NEVER. They click on pdf files, and adobe reader opens them. There is no reason whatsoever to have a shortcut on the desktop. Stop putting it there ever update Adobe, it is just annoying.
Also on Adobe reader. You are a free product. Version 10 or X is out. Why are there still updates for 9, and why doesn't it just update to 10. It is a newer better version, when I check for updates just move me to 10 or X don't just update 9, that is dumb. You are a free product.
