The problem is that once a data transfer has been initiated (For example, let's say you're streaming Pandora), it can't be reassigned to another transport medium.
If I start streaming on 3G, it will remain on 3G the entire time, despite me having WiFi. That's the really nefarious part of the shortcoming, it can lead to unintended data usage.
On Windows Phone, background tasks may periodically execute, which may among other things request network resources (For a streaming agent, or a background transfer agent). This has the effect of gobbling up data usage.
So if Pandora is started on wifi and the phone goes to sleep, Pandora would stop, right?
Periodic background data usage while the phone is asleep should be fairly minimal, I can't imagine that would be a problem data wise ( speaking as someone with a 300 meg data plan who typically only uses ~70 megs of it).
Sure it can be reassigned on the fly. Works on Android and iPhone. http://en.wikipedia.org/wiki/Roaming

What about the cell data connection (3G, LTE, ect)? Does it disconnect when it sleeps as well? That would be kind of a deal breaker for most people I know.
If the data connection is stil active, then why does it matter that it takes a while to reconnect to wifi? Is the switch over noticeable? Do you have an extensive LAN that you interact with on your phone often after waking it up? I don't quite understand the issue you're having.
