"My whole personal computer" on just an external hard drive?
The idea is simple.
I like to have a computer that I can take anywhere with me, run it at any place that has power and internet. Everything on the computer is the way I left it every time, it has all the programs that I use, all the music I listen to, all the private stuff that I'd prefer noone else saw. My own personal computer that I can take with me anywhere.
That's called a laptop, right? Yeah, I have it.
But I'd like to take the convenience even a bit further. At any place that already has a functioning computer, I would like to have ALL of that without having to carry a whole laptop with me, but only at most a couple of hundred grams that fits into the pocket of my coat.
I take it that moving the whole thing to the cloud is not there yet. It will be one day, hopefully soon, but not yet.
But how about external USB hard drive (I think flash stick is a bit too small)?
Well, I see a bunch of Linux distributions (Puppy Linux, Damn Small Linux) that claim to be able to do exactly that.
And I am wondering... is this actually true? Will it REALLY work? I presume I won't be able to play full-blown computer games and thankfully I don't need that. But all the other things? Is it really possible that I can just connect an external hard drive to a random computer and it will boot up reasonably fast time in 90% of cases and it will work just as well as having my laptop with me in 90% of cases, except a bit slower? No rampant compatibility issues, no huge amount of time wasted trying to get the stupid thing to work... In general, can I really honestly achieve "just as if I had carried my own physical personal computer here" by carrying around just an external hard drive?
(I would have two external hard drives, one in use and the other a backup of this, updated every week or whatever.)
