Adobe useful or not

You have to pay to use it. If you don't know what Adobe software is, there are many programs in the Adobe line, then you don't need it.

Haker007, good evening.
There are many Adobe products, but which one do you refer to?
There is also Creative Cloud and PDF related Acrobat.

It ’s about price,
For example, Acrobat Reader, an application for viewing PDF documents, is free, but Acrobat for editing and creating PDF documents is charged.

Whether it is useful depends on how you use it, so you can't just say this post alone.
