From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

To go back to basics, why is FDE not suitable for your needs?
Simple convenience. I usually don't have the time to wait one or two minutes until my full disk is decrypted (I am often late and the only person in a group meeting who brought a laptop for taking minutes).
I also use a weird keyboard layout (Neo 2) and I never got grub to load with that layout. Typing a 40+ passphrase in QWRETZ is just cumbersome to me.
Also: I hate to admit it, but I am a bit vain and simply would like a nice gui for entering my password.
Edit: I forgot to add that I'm playing with the idea of getting a surface tablet and installing linux on it. Then I couldn't count on awlays having a usb keyboard with me.
You can setup FDE that utilizes TPM like Windows does with bitlocker, in such a way that your backup phrase is only necessary if something about your hardware changes.
Last I set it up however, there wasn't any easy/automatic way. Searching "luks TPM" should get you started.
I've been using this guide for ages.
