Just like the title says I'm looking to pickup an inexpensive laptop for bitcoin cold storage. Any ideas?
Lightweight, highly portable, good battery life and cheap would be a great combination.

It should be easy to pick up a used laptop on ebay.

I'd get an old Android phone. A lot more portable, easy to hide, easy to charge. Just turn off WiFi for security.

just get a cheap netbook, something that can be had for $100.. that or you can swap out your hard drive from a desktop.

Craigslist.
When you get it, delete the Ethernet driver files. This will take the machine offline permanently.

maybe a bit offtopic, but some time ago I was thinking of a cold wallet/general password storage based on an android phone with a camera (and working screen). communication (including possible wallet/password updates) solely via QR code exchange/on screen keyboard. i didn't find anything suitable, but should be pretty straightforward to implement.

I would recommend using an old notepad (and if paranoid then consider removing the WiFi card and perhaps blocking Ethernet and modem sockets if applicable) then using a "live" OS (so always boot from USB). From a major computer store complex in Beijing I managed to pick up one for under 100 USD (although the seller was rather stunned that I wanted the WiFI card *removed*). And here is a picture of what I did to the sockets of it.

A raspberry pi combined with a battery pack and a case would work out for these - except you'd need a screen, mouse and keyboard. Depends how portable you need it to be I suppose. The Pi would set you back about $30 and depending on the other addons you would probably spend about $100 all up. Alternatively you could buy a cheap second hand notebook, but the battery life probably wouldn't be that great.

Agreed that the battery life isn't too great - but it is enough to do at least one transaction (and generally when you are moving from cold storage to hot you only would be doing that).

Theoretically fine. I think the paranoid would say something about the machine being air gapped offline etc

Yes - I do *air gapped* so it doesn't matter how badly virus ridden the original OS is (or the one you boot). By using the CIYAM Safe ( https://susestudio.com/a/kp8B3G/ciyam-safe) all communication is done via QR code (i.e. by webcam not by USB or any other *wire*).

Just turn off WiFi for security.
That's not good enough for cold storage. Set a password. Set the phone to Airplane mode, then turn the phone off. Remove the battery, store it separately. Consider the use of a safety deposit box.

Yeah, a netbook is perfect. Small, cheap, and you can rip the wifi card out.

Highly portable and cheap computer? Perhaps you should consider purchasing a Raspberri Pi.

Problem with a raspberry pi is that then I would also need to find a monitor, keyboard and mouse to plug in, in order to do any transactions, which would be nearly impossible to have ready access to that stuff on-the-go. Problem with true paper wallets is well, its too easy to damage, get moldy, ink to smear or just simply lose it etc.
I do like the netbook with removing wifi card and ethernet drivers and your ethernet port "mods".
However, even more interesting is the idea of a phone in airplane mode. Especially if I could get a full disk/OS encryption (I think android tablets have this function? not sure if the phones do?) AND get electrum on it and somehow sign online transactions with it..... Electrum is a must for me.

One potential issue with any laptop/PC, regardless of what OS you run is that the bios could be hacked and unless you physically remove wifi and bluetooth capability you will never know if there is a keylogger etc in place. The good thing about cheap chinese phones as cold storage is that they don't generally support google play but you can side load mycelium from an sd card and disable BT and wifi.
Btw I have a really nice tosh r500 portege (2.2lbs and 12.4" screen, 128gb SSD) that I'm probably going to give away but I won't be back in the US for another month or so. It runs linux pretty well but with w7 the browser can be a little slow.
