rofl. yeah i hear ya. XP has soooo many vulnerabilities and problems, as an IT professional who works on multiple systems daily, it is my most hated operating system to work on. honestly, i'm not all for microsoft either (and i loathe apple) but windows 7 is honestly a great OS, IE 6 was crap, 7 was crap, 8 was crap, all very open to vulnerabilities, IE 9 is great so far!! extremely fast and the ability to use the pc's graphics card to render images on the screen greatly reduces the load on the cpu thus allowing most pages to load very quickly. firefox is a great browser, but it has many vulnerabilities as well...only a few less than IE8. only google's chrome browser has fewer vulnerabilties. as always, you can't please everyone.
on a side note
before you bash a program for whatever reason, keep in mind that those of us who work on, design, set up, repair, etc computers often find that most crashes, slow performance, shut-downs, or problems come from problems with the pc where the user has messed up the operating system, installed a conflicting program, NOT installed a program correctly, has missing required files or updates, or has infected their system with numerous spyware/adware/malware or viruses.
