Full TV Episodes on Computer

Just researching this - seems this year, there are more available free, so the question becomes, are we at a point where we can stop buying recording devices, toss the old VCR, stop rushing home from yoga classes, and watch when we have time? YES!!! I certainly hope so -- and I don't really want to do the 'marathon' watching from Netflix, where there are 4 shows on 1 DVD, and I end up staying up too late, watching one after another! House, for instance, is on 8 days after initial broadcast...now I am setting up a little chart for myself with the web links, times/dates/fav shows - so I know if it will all work, and when to watch -- the trick will be to keep track of Episode names / numbers...which I don't need to do when I just rush home from Yoga on Monday nights for House at 8:00!!!
