Hmmm...there are quite a few things.
I second the Kindle Fire. While I have a laptop, and basic Kindle, I love my Fire. I'm on it all the time, reading, watching videos, playing games. it is the best.
My dishwasher. My first two apts did not have one, and this one does. Now, if I could have my own W/D, I'd be set!
My DVR. And the vast array of channels FIOS offers. I don't even watch half of them, but its nice to know I can usually find something on, esp since I don't watch most network tv. And the DVR is amazing. I can set to record anything and everything, and when there isn't anything on, I have a "stash". And on the same note, On Demand. If I miss or forget to record somethning, voila, there it is.
The Internet. I think back to how I used to find stuff out. PHone calls, resaerch in the library, etc. Now, anytime I want something, and want it NOW, i just go online and there it is.
