Nowadays, if a service isn't multiplatform and/or doesn't sync or connect to third party services and hardware, I don't want it. Even if it is available on all platforms I currently have, if it can't integrate with any future platforms I might have, I don't want it.
Similarly if I have to update things manually, it's not worth really worth it. Tracking services that require me to manually input too much in the age of automation, is not worth it.
