When you store your Bitcoins in a traditional web wallet you put your Bitcoins at risk of being stolen, lost, or confiscated. Here is a list of ways people have lost their Bitcoins through use of a traditional web wallet:. If you keep your Bitcoins on your computer, when your computer is hacked or stolen your Bitcoins can be stolen. There are a number of programs that will allow you to send bitcoins from your mobile phones.
Some are simply mobile interfaces to web wallets and suffer from the same flaws. Some are the same as desktop clients and can suffer from malware or theft.
A USB flash drive is just storage for private keys. It means that when you want to make a transaction, you must attach your drive to the computer and let your bitcoin software read the keys from the device. At this point, your private keys are accessible to viruses and malware, just as to any other software on your desktop computer.
On the contrary, TREZOR is a single-purpose computer, which stores your private keys and actively signs transactions without sending your private keys to the computer. When you want to make a bitcoin transaction, your bitcoin software just sends a transaction template to the TREZOR device and asks for a digital signature. You will then confirm the transaction by pressing the hardware button. TREZOR will sign transaction internally and send the digital signature back to the computer, without leaking your private keys.
This is a vulnerable point because a virus has access to the wallet file and can read your passphrase from your keyboard. On the contrary, TREZOR never sends private keys to the computer, because when you want to send some coins out of your wallet, TREZOR asks bitcoin software for payment details, signs the transaction internally and then sends back just a digital signature of the transaction.
There is a significant difference between the two. The Yubikey is a device which helps the service to verify that it is actually you who is signing the transaction. However, it does not protect you against signing a different transaction than you intend to. A paper backup is a quite safe method to protect bitcoins, but you still need to load private keys from paper using a trusted computer to send your coins to somebody else.

What if my computer that runs my bitcoin wallet is stolen? What happens if my recovery seed is stolen? What happens if the SatoshiLabs servers are hacked and the firmware signing key is stolen?
What happens if the SatoshiLabs shuts down? Why is the device not covered in epoxy? How about MCU glitching? What if the RNG is flawed? Is it possible to flash the device?
