I love the possibility, but I can't read them on-screen nearly as well as normal paper ones. My attention flickers while I get a headache :P
Staring at a computer screen is not my idea of pleasant reading.
So I prefer the old paper ones, but I really like the opportunity to acces them online. You can't always get the old paper ones.
3d option, with a hint of the first (as I can still enjoy them when they're on-screen
).
