At least you could get Adobe on there easily. Windows 8 has an issue where Windows Installer stays dormant on your computer doing little or nothing, but blocks stuff like Adobe Reader from downloading unless you end the task. Not that it tells you that's what's causing the problem, of course.
I had to download Reader because Windows 8 no longer starts with it out of the box, in favor of its default PDF reader that (like all the new default programs on Windows 8 ) is terrible, lacks functionality, and is designed for touchscreens but foisted on desktop users anyway.
How much functionality does it lack? You can't jump to a page number on it.
