Well, yep...
they're out. The new Magic Trackpad 2 features Force Touch and a larger edge-to-edge glass design with 29% more surface area. The new Magic Mouse 2,
while keeping the same form-factor also has a built-in rechargeable
* lithium-ion battery and redesigned internal structure that includes fewer moving parts.
The changes to the new keyboard and mouse are, to me, crap. The trackpad is the only worthy upgrade due to force touch, but for some reason they found it necessary to increase the SRP of all accessories. That being said, even the new keyboard is better than the new mouse and that's saying a lot considering the it's still lackluster despite the touted improvements.
With the Magic Mouse 2 released; definitely get some other mouse if you can't see yourself using a trackpad 100% of the time and also if you see yourself needing a mouse for all those times when precision is required. And the new accessories are even more expensive; the changes can barely justify the price hike. The trackpad is worth it, but again, it's pointless if you're solely betting on the chances of you getting used to using only that.
*You can't use the mouse when it's charging by design. But it shouldn't be a problem since Apple promised that two minutes of charging a dead mouse will provide enough power for about nine hours of use. A two hour charge will give you 30-days use of the mouse.
