Cons
Con Too expensive
The icons I need are in the pay plan.
Con You will never use all icons
This means you'll have a lot of useless data (unused icons) being load into your application.
Con Font Awesome slows webpages

Con Subscription model
Illustrator CC requires a $19.99/mo (minimum) subscription to use. Adobe no longer sells previous versions of Illustrator.
Con Heavy use of CPU/RAM
Con Steep learning curve
Con Very slow
Even in very good computers Illustrator is very slow.
Con You never truly own this software
As soon as you stop paying you to lose access to the software. This should be illegal.
Con Install useless and intrusive software
When you install any Adobe product it also installs lots of useless and intrusive software and services.
It adds two services and up to three auto-starting software that runs when you start your operating system and keep running constantly. One is for auto-updating, others for "checking" if you are not a pirate and some others that seems to be just to collect information.
Con Imprecise coordinates
Oftentimes your 140 is 139.9997 and as a vector program it doesn't rely much on precision.
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 Buggy
Software can be very buggy at times.
