A year or two ago - definitely. But as of today, I would disagree. Apple has been shipping BTLE in their devices since the 4S. All flagship Android phones have been shipping with BTLE for over a year (with official SDK support added in 4.3). You can pickup a $10 USB BTLE dongle and it works out of the box with bluez (Raspberry Pi works great).

Android 4.3+ adoption is barely over 10%, while iOS support must be in the 90% range.

EDIT: actually 14.2% [1].

on "x% of 1 billion is a lot": it's still way less than 90% of 500m devices, and you're still frustrating the majority of your user base.

The last time I picked up a $10 BT dongle, it had "CSR 4.0" written on it but was neither CSR (Cambridge Silicon Radio) or 4.0. Any hints?

Heh, name and shame the supplier? I ordered one of those from Adafruit. It was noticeably of "Chinese street market" build quality, but works great with a Raspberry Pi.
