Close, but not exactly the same.

No, as maintaining that would make little sense (this isn't a very 
common question and it usually doesn't make a big difference). If you 
want, you can practically do everything you can do the other on the 
other as well.

You can install new software when using the live DVD as normally. The 
applications installed are then stored in your RAM. However, once you 
boot, you will have to install the software again (and create all work 
again, unless you saved it on some other storage media).

If you use a USB disk with persistence, then you can install 
applications and save documents as normally. But then again, that's like 
a regular system anyway, on an USB stick.

That's true. I believe we are inheriting this function from Ubuntu desktop.

For the record, the argument for doing this like it is done that is that 
a partitioning tool is often useful on a live disc, but since it's also 
a very dangerous tool if misused, it's better to not install it for the 
desktop. This way the user needs to take the extra step to install 
GParted, but on the other hand, they will also have more time (and 
steps) to think about what they are doing.

There's a flaw in your logic. If applications couldn't be installed (and 
thus files not saved) on a live disc, how would installing KeePass make 
any sense, since you would always need to set it up again?

This can be done already.
