magsafe 2 for retina display macbook pro

I've had two different MacBook Pro's since 2006... I went through 4 magsafe power adapters as the cable coming straight off the connector always began to permanently bend at the magsafe connection point such that I didn't trust it from an electrical safety point of view (after seeing one arc at that point a time or two). Then when I bought what would be my 5th power adapter, much to my positive surprise, Apple had done a redesign that had the cable coming out at a right angle with repect to the way the older ones had the cable come out... They also beefed up how the cable comes out of the magsafe end.

Now I see a picture of the 85W power adapter for the new Retina display macbook pro I am planning to buy soon... And it looks like they've reverted to the old "wire straight out from the connector" approach...

Is that true??? That would be a significant step backward for me as where I have to plug in my mac (to the right of where I sit) having a straight cable coming out from the left of the mac is just going to cause me to start wasting power adapters again...

Might I be able to continue to use the 85W power adapter I currently have on my 17 inch 2009 macbook pro??? And it's not the original power adapter but one I bought maybe in 2011 or so... I love this one where the cable leaves in the direction heading out away from the top of the mac rather than the ones that came out straight to the left... And the picture of the new one appears to come out straight to the left again...

And what do you even call the power adapter I have that I bought in about 2011 where the cable comes out at a right angle to the magsafe connector itself???

Any help folks can provide on the questions above would be much appreciated... thanks... bob...
