None taken.  
As for the features people always loved Cannondales for : I love predictable, precise handling and good value for money, and I'm sorry to say that both the F400 and F6 failed on those criteria.  
The F400 is a very distant memory nowadays and I'm not sure if I even want to remember how bad it was, so I'll only go in-depth on the F6.
I'm perfectly aware that the disintegration of the SX5 mech and all the broken shifters were SRAM's fault, not C'Dale's.  I'll even accept that the broken V-brake arm could have been a freak accident.  So I'll take the reliability (or lack thereof) out of the equation.  Still it's no fun if you can't complete a single trip without technical problems.
However there's no excuse for the amount of frame flex the F6 had, or the resulting catastrophic handling.  IMO those kinds of issues are in a completely different league than rotating grips or excessive tyre wear.  I could live with rotating grips, but not with that kind of handling.  
Actually that's not entirely true.  I wouldn't be able to live with a rotating grip either, but at least that can be fixed.
Even if it really is an entry-level bike, a brand like Cannondale, who pride themselves on their frames, should do better.  I can understand that they skimp on the groupset, but not on their frames.  It really reminded me of a £99 Decathlon Rockrider.
And it's not like they used thin-walled tubes either.  I'm actually surprised that a medium size aluminium hardtail could weigh 32lbs, especially one that costs 899 EUR (£750).  For close to half that price you have lighter, better equipped bikes that can actually take a corner without trying to kill you.
She was beautiful though ...
		
		
	
	
Maybe a £2K+ C'dale is actually a good bike.  It probably is.  However I'm not keen on spending more money to find out.
