The cables of Apple's MagSafe charger are also quite crappy, they tend to fray after 2-3 years of use. I hope that gets better with USB-C and if not at least you'll have better third-party chargers available.

… buy cables with strain relief, and/or replace a $10 cable instead of an $80 power supply.(In 4 years I had to buy two bricks. Those thin cables are shocking. Still, Magsafe is such a nice connector, I wish they were all like that... instead of these large phallic daggers that will inevitably break their precariously-soldered ports.)
Edit: Reading other comments, I guess I was lucky.
Well, depending if these new macs use the USB-C port for charging _and_ regular USB usage, another laptop with a standard non-magsafe charging port could actually be more optimal for some/most.
First, it's a good thing that we're converging on a standard. Standards mean not only that we can safely buy components from third parties (for instance, buying reputable, reliable USB Type C cables from places like Monoprice or whomever), but that we can borrow charging cables from others relatively easily. We've had a taste of that thanks to MagSafe's ubiquity, but a USB-based spec potentially broadens that.
Second, USB battery packs (admittedly a slightly niche product category, but one that's been growing rapidly in the past few years) could potentially be made to charge Macbook Pros now. There are some battery packs out there that support MagSafe today, but my sense from shopping around every few months is that the best option continues to be to buy a battery pack that has a standard electrical outlet, and carrying that big bulky MagSafe AC adapter with me. Transitioning to a USB spec (should) permanently open the door to portable battery packs, third party AC adapters, etc...
Third, USB power hubs (again a slightly niche product category, depending on whom you ask) can consolidate all of the AC adapter functions that devices need for charging. I'm already nearly there --- my tablet, battery pack, bike lights, phone, and watch all charge by USB (heck, I have a charger for my DSLR's batteries that uses Micro USB), and a single AC adapter for those devices is both tidier and easier to pack and travel with.
I agree that MagSafe's really nice and I'll be sad to see some of the benefits go, but particularly with MagSafe 2 they've overcorrected in my opinion by making the threshold strength necessary to break away too low, and it's caused me to seriously reconsider whether the frustration of all these inadvertent disconnections is worth the benefit. I see at least a few reasons to be glad that the next laptop I buy (maybe in a year, certainly in three) will probably be able to charge via the same (reasonably priced!) AC adapters and battery packs that I'll own for my peripherals, and that if I'm really up a creek it'll be more likely that I find someone with a compatible charging cable, since USB is (and will continue to be) pretty much ubiquitous.
I'm assuming that they will do this with USB-C.
I don't see any reason to go off spec given that they should be able to go up to 100W, but I may be wrong. Or Apple might come up with some hazy excuse for why the existing standard was no good. It'd be a real shame, though.
