I like it here, But I do miss a fair bit:
1) Affordable craft beer (I love American stouts & Porters). English ale can be very good, but I am a craft beer snob. It is a very expensive hobby here.
2) Buffalo Wings (The stuff here sucks)
3) Actually, good casual dining (Casual chains in the UK are awful and ridiculously priced) Some pubs offer great food of course, but that depends on where you live
4) Driving in the US. Far from perfect in the states, but I hate driving in this country. Too much traffic calming nonsense, and its very unfriendly if you don't know where you are going.
5) Movie theater popcorn. The stuff here is trash. I lived in Texas and really miss Alamo Draft house.
6) Convenience: Pretty obvious, convenience isn't as important here.
7) Easy access to European products in local markets. It's easier to get things like Buffalo Mozzerella and San Marzano tomatoes in the states than it is here. (Unless you're in London, I'm sure)

Target shooting- I miss my rifles
9) Cocktails that are reasonably priced and actually contain some booze
10) The sun
There are pretty compelling advantages here though
1) The NHS (while it lasts)
2) The proximity to Europe (When we can afford to go)
3) The police are so much better here. So many US cops are awful
4) A pretty low probability of getting shot (though it does happen here still)
5) Great produce.The eggs blow away any I've ever had in the states
6) It is a gorgeous country. On a nice cool sunny day, theres few places much better IMHO. Little snow, few 90 degree days.
7) History!!!!
