Much of TechEd will be available online this year if you are unable to attend. Personally, I've opted to attend MMS for many years in lieu of TechEd since I feel very passionate about the Microsoft solutions for Management and Operations. I will definitely be catching up with as much TechEd as possible from my home office, through this portal.
