Well, the hope that iDraw would grow into a low cost alternative to Adobe's Illustrator just got a little murkier ...

There's also Affiinty Designer, which is a decent, low cost Illustrator alternative
Mwhaa... Don't overstate things.. It's a mega cool app with lot's of professional angles to it that makes it come close to Illustrator but when working with Affinity Designer for real you can clearly feel and see it's only a one year old app.
Illustrator is matured over the past 300 years, it has the Adobe famous workflow - this means Photoshop, Illustrator and almost any other app work the same way and connect so brightly with each other without yourself noticing it until you switch to another app that promises the same quality but they feel weird because it's not Adobe making them.
Of course give Affinity Designer 2 or 3 more years to mature and get some solid updates and it will also be at Illustrator level or even better, everybody can see there are talented people working on this software and no cowboys. I'm totally a fan of the Affinity software from the first day, what they are doing is the reason I still owe a Mac computer.
If you'd be planning to buy apps like iDraw or Pixelmator today I can't imagine why you wouldn't invest +20,- more for Affinity Designer and/or Affinity Photo because those Affinity apps are for real.
