I held off on Windows 10 for as long as I could until Adobe, and therefore my job, required it. Now this nonsense. I hope this isn't the start of them joining on the web DRM bandwagon.
On all my Macs, Preview is set as the default app for handling PDFs, and I use it for signing, adding text, rearranging and deleting pages; works flawlessly. Fuck Acrobat Reader / Pro.
If I need to do something more complicated, I'll open it in Illustrator.
