Yeah, I don't really see the suspension as something worth paying more for; the only potential "feature" I can imagine is it being significantly cheaper, which seems tough given how cheap a VPS already is.
A suspended machine only costs its disk usage to the hoster. You can have 800 of them on a machine with 4TB SSD. You can't say the same for VPS at all.
The service seems neat, but the pricing seems more to be a novelty than a real service. Maybe I’m missing something.
Can be pretty fast.
