SFO-OAK is pretty easy (despite that ridiculous, overpriced cable car at OAK).
Tokyo's great too even if you don't understand Japanese. Haneda is in a great location and has tons of connections. Haneda to Narita is also pretty easy (bonus: monorail).
Airports are, by design, generally out in the middle of nowhere and their connectivity suffers as a result. You get things like London where Heathrow and London City are reasonably accessible, but things like Stansted are out in the middle of bloody nowhere.
Sure, and from Liverpool Street the Stansted Express is quite expensive (> 30 GBP) especially when compared to simply taking the tube to Heathrow (<= 6 GBP). That is, IMO, bordering on expensive enough to consider that poor connectivity.
I always take the Heathrow Express, so I guess you aren't on an expense account! If I read the rate card correctly, the Stansted Express is cheaper than the Heathrow Express.
