heck, I still drag around an old 2005/06 era 8.9" netbook I picked up for $300. It's tiny, gets on the internet ok, can connect to an external monitor/kb/mouse to turn into an impromptu desktop in a pinch, has a 250GB HD and two SD card slot so I use it to offload photos from my sd card at the end of a shooting day while out traveling and the other slot lets me expand the storage if I need.
I can use it to review my photos from the day and do some minor edits with gimp.
Bonus, it's about fast enough to run dosbox or scummvm and play standard def movies in vlc well enough. I can even emulate a Sega Genesis and hook up a controller and use it as a mini console.
It's been around the world with me many times, fits into the space a large paperback book would take. It's not "modern" by any stretch, is pretty beat up, but the large cheap storage device that happens to be a computer is very hard to come by these days. I've seen some newer devices with better specs, but they all insist on tiny SSDs, like 32GB drives, so they're an instant no-go.
