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*).

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).

Lightweight, highly portable, good battery life and cheap would be a great combination.
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.

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.

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.

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

just get a cheap netbook, something that can be had for $100.. that or you can swap out your hard drive from a desktop.
Do you really mean Cold Storage? If so, why not a paper wallet? cheaper than any laptop and far easier to secure/hide, plus the added advantage of never breaking down!Try this: https://www.bitaddress.org/bitaddress.org-v2.9.3-SHA1-7d47ab312789b7b3c1792e4abdb8f2d95b726d64.html

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

Just like the title says I'm looking to pickup an inexpensive laptop for bitcoin cold storage. Any ideas?

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