Hello gelotologist! I understand that switching to differrent platform in creating designs or logo is really hard since you will not be very accustomed to the locations of the tools and the shortcuts that you have memorized to create fabulously.
And its okay to try out some other applications that your friends told you to use because you will be able to experiment and find out what they are saying is better.
As for my suggestion to you and to all who are reading this thread that it might be useful even just a little, creating designs for business for you or for a client is very fullfilling. Because you will see what you have created have been use and have change the life of someone or somebody.
I design using lots of platforms and found out which one will be much better for a certain project. First I use Aldus PageMaker and Print Artist, after sometime I use Corel Draw, Corel Photopaint, then afterwards Adobe Photoshop and Microsoft Publisher. If there is an effect I I can't do or don't know in Adobe Photoshop, I'll do it in Corel Photopaint then vice-versa if I need vector before I turned it to a jpg I will use Corel Draw or Publisher. So it is better for you to know something about other platforms instead of just one.
