I think that when one has 0.01 bitcoin and wants a secure wallet, hot wallet which happens to be offline at the moment is a normal choice.

Absolutely. I have a hot wallet on my phone which is pretty much online 24/7. I've had such a hot wallet for years, which I've spent from multiple times a week, and I have never been hacked and never lost a single satoshi from it. It's entirely possible to have a safe hot wallet. However, I am under no illusion that such a wallet is by far the riskiest wallet I own and is by far the most likely wallet I own to be hacked or exposed to malware. I only ever keep a small daily spending amount of bitcoin in it (certainly no more than 0.01 bitcoin as you say).

But the discussion here is about cold wallets. The wallet I describe above will never be a cold wallet. A mobile wallet which only goes online once a year is also not a cold wallet. It might be safe so far, but it is never as safe as an actual cold wallet. I could drive for 10 years without ever wearing a seat belt and never suffer any injuries - doesn't make it a good idea.

Definitely I know we talk about cold wallet. My point is that it's not necessary to take very strict measures if you don't plan to hold it for a very long-term or if you don't plan to hold much bitcoin, that's why I am saying that most people who say that they want cold wallet, will safely keep their funds with hot wallet which happens to be offline at the moment.

Maybe so, but there is also WiFi, Bluetooth, RFID, NFC, and other connectivity modules to consider too. Disabling all of them without breaking the phone is difficult. It is far easier to start with an old laptop which does not have the majority of these at all and then just remove the WiFi card.

Most of this can easily be disabled with Airplane mode, so it's not that hard, unless you want to permanently remove them.
Laptop is better for many things, but you can't disable or remove anything unless you have specific models ^{(example old Thinkpads)}, most laptops today (sadly) have almost everything soldered on board.

The problem is that you can't actually trust your Airplane mode on your smartphone, nor on your laptop. I think, there are laptops with motherboards that do not come with built-in Wi-Fi.
