Some of my favorite things about England (or should that be favourite?):
Trains!!! And public transportation in general. I suppose if you come from a place with good connections (like NYC or something), it's not as noticeable. I thought I'd die without my car before I actually moved here. Now, I am thinking that I don't really need one ever again (and I don't even live in a city with a metro!).
Tea and biscuits are a daily occurrence, rather than an occasional luxury.
Being able to see what's really going on in the world, instead of sanitized corporate news.
BBC TV/radio, and Film 4 (it's free now!).
Nearly everyone knows how to read a proper topographic map, and you can buy them in any bookstore (unlike the States, where you usually have to get them from overpriced outdoor goods stores).
The hillwalking tradition.
