The reason I questioned it is because your doing yourself a disservice by using IE. Besides all the security flaws, its the worst standards compliance browser and people are pushing standards pretty hard now that we have Firefox, Opera, Chrome, and Safari all being all standards compliant. At some point some sites (smaller ones at first) will choose not to support IE.
IE8 FINALLY is CSS 2.1 compliant which is at 5 yr old standard. CSS 3 is already starting to be used.
