they may, but after having a pro for a year, i sold it with 100% battery life left

Having a new connector allowed them to change the voltage safely.
If they simply changed the voltage without changing the connector, lots of people would connect the new 20V adapter to an older 16.5V laptop and it could cause problems.
There's a reason they made the MagSafe-to-MagSafe-2 adapter but not the other way around.
So while the voltage and connector are not directly connected, they are indirectly related.
So, the adapter is essentially upping the voltage from the lower adapter to the new computer?
No, the new computer is just compatible with the lower voltage as well. But if you were to put the higher voltage charger in an older MacBook, it could damage it.
Why did they go back to the old design with the cord sticking straight out from the side?
Now when I use its on my lap, I keep disconnecting the laptop power with my knee, because it protrudes out too far.
Plus it was nice to channel the cord away from you not out to the side of you.
Not a huge deal i guess, but I was very happy with the last generation of MagSafe and this is a step backward, imo.
The adaptor and old MagSafe does kind fix the channeling it away from you issue, but it still sticks out.
Oh well, love the laptop, just wish they would have left the charger alone it was great the way it was.
Probably not.So, the adapter is essentially upping the voltage from the lower adapter to the new computer?
Good point about the voltage. As for the L shaped MagSafe, I saw my friend's 13 Air slide off the table when his dog tripped on the wire. Good thing I was there to catch the unit or it could have been a 3 feet fall on the hard marble floor. I agree that the L shape is a bit too secure.
From my experience: The T design works as intended, the L adapter doesn't.
If you just want a quick and easy hookup the L design is great: low profile and magnetic.
If you want something to actually keep your laptop off the floor when someone trips on your power cable: you want the T as it actually disconnects and doesn't hang on the machine like the L does.
My old T adapter did have issues with fraying at the t-junction though, so hopefully they fixed that.
This! I don't know why people are whining about Apple going back to T-shape. If anything, the entire point of MagSafe is to disconnect easily to save your laptop from hitting the floor. L-shape is coming from the first gen MB Air where it was a necessity, but bringing it to the whole line was a disappointment to me.
why was it a necessity??
Wow I had no idea! Does that make the newer airs slightly thicker?On the 2008 Macbook Air the Magsafe port was at an angle on the bottom of the laptop:

There just wasn't room for the T-style adapter. That was the first of the L-style adapters.

So just because your corporation doesn't see the use for it (yet), that means it's nothing more than an additional feature to hype?I work in a large scale enterprise where we use Macs & Windows laptops. The number of Macs in use has grown dramatically in the last few years. Approx 35% of us use new MBP's, MagSafe is a solution to a problem we don't have.
The general consensus is it's more of a nuisance than a benefit. That's not a criticism, just an observation. It is what it is.
Quite a few people work both in and out of our satellite offices where they use whatever desk is available. Therefore they have loose cords plugged in here and there, it's just not a problem. Every other brand of laptop has had the same basic power cord for decades. We are all adults & know how to be careful.
It seems that Apple designed these as an additional "feature" to hype, thereby fulfilling their craving for more talking points. Who knew?

Think of all the college students using these. Besides, if the MagSafe port saves your ass just one time, that's already well worth it (cuz it just saved your 2 grand laptop).
Besides, there are no downsides to MagSafe. I find it's even easier to plug/unplug than the traditional circular power connectors.

Yeah, I^2R heating.Higher DC voltage allows to transmit the same amount of power with reduced amps (current). Less current means less heat due to resistance in the wires and such, so it's more efficient.
The reason it's 20 Volts DC instead of something even higher like 100 Volts DC is for safety, cuz 100 Volts might be deadly. 20 and less is still pretty safe.
