Could you please elaborate on where the suckiness lies? Was it particular devices, or particular phone manufacturers? Or was it something wrong with the Android BLE APIs?
Everywhere possible:
1) Different levels of support on different hardware
2) Doesn't support half the BLE spec (Peripheral)
3) Limited functionality on the Central side, only supported 4 Peripherals last time I checked
5) Buggy in general
Just like we don't trust Apple to build cloud services that don't suck, we don't trust Google to build a consistent hardware/OS experience across Android. This is stuff that is not sexy, but it has to be done, and it's exactly what you expect to be done by a company that doesn't have 30+ years in building their own hardware + OS.
