Better battery life is always good, but do the refinements on waking and sleeping carry over at all to jumps?
Specifically, I'm thinking if it wakes faster, it may also jump faster.
For those who haven't used the TB, it isn't that waking or jumping is slow. I'm not sure what is typical for these things, but I do remember reading a few years ago about a keyboard that could connect to two or three devices and someone said it took something like 30 seconds to switch!
But I divide such things into 3 fairly broad categories. Things that take so long that they are really annoying (30 seconds would do that!). Much shorter delays which don't matter much, but which throw off the flow of your work. And the ideal - instant - so you never feel like you're waiting at all.
There was an Apple II app many years ago called "Time is Money". What I really liked about it was if you pressed a key to go to a different section, it came up instantly. One of my brothers didn't think that mattered. His view was, "What does it matter if you have to wait 4 seconds" (while the disk found the right part and loaded it). He was right, technically. And for his personality, it probably didn't matter at all. But for me, I really liked just moving from one thing to another without waiting even a little.
I'd be surprised if that kind of instant result would be possible with a BT connection and a single radio. But even though the TB is quick, even quicker would still be nice.
