There have been plenty of comments about the Jumps on the TB - mostly an idea that they are the reason for the connection issues and that not many people will need them.
I've addressed the connections issue - that is, I haven't seen anything that shows the jumps create the problem. So maybe, since people using jumps will be making connections more often, they simply reveal the problem more easily.
When jumps were announced, I thought it would be nice, but not a big deal, just like many other posters here. But after I got to use it, I completely changed my mind. I suspect many others will too.
So, perhaps folks can post and tell us how many devices you may use a TB with. I say "may" because, even if you don't think so now, if you have multiple devices you certainly MAY change your mind.
In my case, I have an iMac, iPhone, iPad Mini, and the smaller iPad Pro. All are paired with my one TB. I have the iMac actually assigned to two slots - one for normal use and one with any special layout I'm working on. I also have two slots for the iPad Pro, which is what I would take with me on trips. It is possible someone else may want to type on it in these cases so I have a QWERTY layout for them (I use Dvorak).
So I'm using all six. And I could use more, because of the customization possibilities. Special layouts for particular uses, like games - and there could be a good number of those requiring different layouts to satisfy an individual user. If I had more, I'd probably do some more duplicating, such as have QWERTY slots for iphone and iMac.
Oh, I could always load in different layouts. It isn't a long process (30 seconds maybe plus time to go to the app area that does this). But nicer to just have every possibility there permanently and switch in 2 seconds.
