Seriously? This is the earliest beta of this release. Only bricking twice a day sounds "pretty stable" to me.
I've had an iPhone5 since it came out and I've had one instance of needing to hard-reboot the device. Can't remember the details.
OTOH, My previous phone, a Galaxy S2, had far more issues. Multiple times in my ownership -- at least 4 that I can remember -- I literally had to remove the battery to restart the device.
In many ways I wish I had a hybrid device. The fit and finish of the hardware itself is much better from Apple. Some OS features and especially Google-provided web services are much better on Android. (Speech-to-text for one..) But having owned an Android for 2 years and an iPhone for 8 months, the iPhone is definitely, definitely more stable.
In some ways it seems like Apple v Microsoft on the desktop again. Apple controls the OS and the hardware so yes it BETTER be more stable. And it is.
