Cydia has always been up and running, bro. As for USB3, I don’t really have the need for it. My desktop still uses USB2 on the front. In case you haven’t noticed, USB3 is STILL transitioning users from USB2. It’s all logical thinking, cost management, and pure marketing. As for the Delete button, who cares? Backspace, delete, same crap. Also, if you haven’t used a Magic Mouse, then you clearly don’t know that it has a right click because it’s “magic”
You are wrong.
The 8gb GDDR5 is graphics memory. However, it still costs a hefty amount to manufacture that memory for regular PCs.
The 16gb DDR3 would be significantly cheaper but I think it has to do with speeds and voltages, that’s why they’re going with GDDR5 (better bandwidth and speed for outputting 4k graphics? More energy efficient?), but using it with the CPU/GPU is kind of weird. (They’d have to share the memory). Whereas having 16gb of DDR3 ram, then around 2gb of GDDR5 for the dedicated video card would do more justice. I’m just speculating from building PCs
