I've been living in rural Norfolk for the last 10 years, and it has plenty of good points.
Real-estate prices have risen quickly just recently, but it's still cheaper than many other parts of the country. The county's population density is much lower than the average for England, the air is relatively clean, and the crime-rate is well below the national average.
Norwich is the largest city in the region, with plenty of varied employment opportunities, yet there are plenty of quieter villages within easy commuting distance. Although the city can get a little busy at rush-hour, the traffic is still nothing compared to London or other large urban areas. Outside of the city, the traffic around Norfolk as a whole is much lighter, so travel is more a pleasure than a chore.
Around this part of the county we also have the Broads, the inland waterways which are popular for boat travel with tourists and make a nice backdrop if you live in the area (although houses which actually back onto the waterways are
very expensive).
Downsides: Limited work opportunities outside of the main towns, and pay is generally lower than in other areas. If you're self-employed (as I am), don't expect to be able to charge the same rates as you would in the more urban areas of England -- People just won't pay that much.
The very rural parts of the county out in the wilds can be a little drab and windswept in winter as you travel down muddy little backlanes (but the summer days of driving along relatively uncongested roads with the windows down makes up for it!).
