I bloody hate commuting, so I wouldn't! I jacked in a job in the West End because of the commute, and I only lived in Croydon at the time. The vile crowded, smelly trains, being crammed in like cattle with your face in someone's stinky armpit, getting groped by perves etc was my idea of hell.
I don't know what trains are like outside the SE, but in the 18 months when my late DP was commuting from Sussex to London, there was never a week when there wasn't a serious delay on at least one leg of the journey, and several weeks when it was irevoccably fucked the majority of the time. Bad weather, signal failures, jumpers, train breakdowns, broken level crossings, floods, cattle on the line - every week there was something, often several different events.
His 70 minute train journey home should have got him to our local station just after 7, but it wasn't unusual for it to be well past 9pm. And there were quite a few occasions when the trains terminated early and I had to do a 24 mile round trip to pick him up. I had to pick him up from East Croydon once, and brought 2 strangers back to Sussex as well.
If you have decent trains where you live, it might be ok. My friend is in a village in the West Midlands, and she has a far better service into Birmingham than we have into London from our commuter town.
