Travelcards - are they now too expensive?

[rdwarr]

I normally travel to London on business about one day per week. Typically I'll leave home at about 9:30 and return at 6pm. Before the January 2006 increases the price of a One Day Travelcard (from Stevenage) to cover this and all London travel was £13.50.
With the latest increases and a change in the rules governing returning from London at peak times the price is now £21.50! That's an increase of 59%.
Anyway, looking at all the fares it now appears cheaper to travel to London on a standard ticket (£14.80 peak) and use an Oyster card (just applied for one). Has anybody else found this to be the case?

They say that the increase in ticket prices was intended to drive people into using oyster.

I can either catch the bus to work or catch a train and then the tram which takes about 1/2 the time. The train fair has just gone up from £1.60 to £2.30 so an even more impressive 62% price increase.

My OH is just renewing his season ticket. Instead of going for a travelcard he's buying a season ticket to King's Cross and then using an oyster card for the rest of his journey. He's worked out that factoring in holidays and weekends he'll save several hundred pounds.

I don't live in London, but if I visit now I avoid the tube if I can. It's expensive, appallingly overcrowded and getting more and more unreliable.

I am an Arsenal supporter (sorry, someone has to be !). I used to get the Piccadilly line from near Hounslow (ish) to Highbury on a Travelcard but I now get the Silver Link surface trains, cheaper much less crowded and something to look at out of the windows.
