The problem with blackout is that the web drops. When web drops, everything else is 95% useless, no matter the batteries.

Even for work in SketchUp you have to be connected, else you can't get models from the web. Emails? Forget it.

On the rare occasion when that nightmare happens I get my fix from mobile browser which has it's own battery, to keep up with Gmail and to tell everyone I am back in stone age with old farts.

If there is a real (and expensive) need for web & pc, I use bluetooth and laptop to use mobile phone as a modem. It is slow but it works. Means a lot if you work in the cloud and program over the console.

You have an 8 lane crowded highway and you want to transfer a ton of small packets over it. Why use a big convoy of trucks and wait like 98% of idiots out there? Didn't you notice something strange... those motorists that are laughing at your face and passing you by all the time? Why not use them as the means of transport? Maybe because they are expensive in real world, but in digital that's not the case...

I use them. I use software like ReGet that doesn't put out one connection for a truckload of data. It creates in my case by default minimal of 32 (or in serious congestions even 64 and 100+) connections and downloads them all at the same time. It's like a ton of motorists transferring your data around slow moving trucks. I never get less than 100% of my 2Mbit downlink downloading this way.
