10 Speed to 11 Speed for £350, is it worth it ?

I was wondering if upgrading from 10 speed 105 to 11 speed Ultegra 6800 is worth it for £350 (front / rear derailleur, shifters, cassette and a chain). Does it make £350 worth of difference or is it better to save my money ?

Merlin £238 for the shifters and mechs, you'll pick a cassette up for £40 and a chain for £20 if you search.
Personally, I love 6800. I think the upgrade was well worth it

You could spend that £350 on a weekend in the Alps or something really good.
I would follow this advice.
I see some have advocated you save your cash for a holiday or to save it when your 105 is gubbed. This is cycling and you treat yourself often as you deserve it(well this is what I tell the missus)
The value of money is entirely dependent on how much of it you have and the demands placed on it.
If you're struggling to put food on the table then no, it's not worth it. If you have all the money you could ever spend and you don't believe in charity then it doesn't matter what you spend on anything. It's a silly question.
What do you really want to know?
There is also an element of FOBLO (fear of being left out)... they make you believe that 9 and 10 speed components will disappear from the market... which is not true of course, as three quarters of the geared bikes on this planet still work with 7 and 8 speed systems, go figure...
