I think I see this as supplimental....
So at home you have the work station for editing the photo's vid work, work work type stuff.
This thing allows you to have access to most of that stuff and limited editing without having to run two separate computers.
I've been trying to figure out how to do that, ie: have a killer workstation and be able to take a laptop out with me when i'm traveling, etc. The problem with doing this is there's not a viable way to "sync" them up outside of cloud storage or manual copy pasta.
This does that. You plug it in and have access to everything without carying a ton of stuff with you. Nor do you have to plunk that kind of cash down on both a tower and a laptop.
I also see this helping consolidate medical info. One chart instead of 120398120398 charts.
I think if you're even the slightest bit prescient, you can figure out plenty of legitimate uses for a device like this. If there weren't any, then all of the sci-fi programs wouldn't have everyone walking around with one.
I am disappointed in the lack of video chat/multi task though.
