Cons
Con Subscription model
Illustrator CC requires a $19.99/mo (minimum) subscription to use. Adobe no longer sells previous versions of Illustrator.
Con Steep learning curve
Con Heavy use of CPU/RAM
Con No proper selection mode
In a vector-art program, the critical selection mode is the one in which objects must be fully enclosed by the selection marquee to be selected. In the simple example shown here, selecting all the circles should merely require you to draw a selection rectangle around them. But in Illustrator, there's no way to avoid selecting other objects as well, even though they're not totally enclosed by the selection box. Year after year, Adobe fails to fix this bizarre oversight, making Illustrator a tedious pain to use.
Con Imprecise coordinates
Oftentimes your 140 is 139.9997 and as a vector program it doesn't rely much on precision.
Con Has ads
Displays advertisements (in a sidebar on the right - no popups etc).
