Sling beats Apple to the iTV Punch?

It costs $100 less than the iTV is predicted to be priced, it works for both Macs and PCs, it streams any video from any source to your television, and it works with wireless networking and Ethernet. Is the SlingCatcher an Apple iTV killer even before iTV hits the stands? At the very least, it proves that Apple's iTV pre-announcement has already changed the market and forced all competitors to rush their offerings to the public before Apple creates another "standard".
