Good for you. You are obviously a power-user and any restriction placed on MSIE will not really affect you as I assume you are using some other browser anyway.
The fact remains that XP is almost a decade old, and just because your OEM paid $20 for XP 9 years ago, does not entitle you to having free support, patches and new APIs backported to XP forever.
Microsoft has officially ended regular support for Windows XP and are now only providing patches/bug-fixes while on extended support until 2014.
Windows XP might work for you, even under these conditions, but don't delude yourself into thinking it isn't outdated just because it works. When the vendor stops supporting it, it is outdated.
Unless you are running on a machine with less than 1GB ram, I see no reason to cling on to XP.
