OS:
I have not tried 10.1 yet, mine is running 10.0.90. The OS has been very stable, I have installed 20+ Android ported apps, 30+ native apps, and I have never experienced slow responsiveness or random reboot - not even once.
Battery:
Previously I owned Nexus One/Galaxy Nexus, as well as 9900. To compare their battery life:
9900 (2 hours usage) < Galaxy Nexus (2.5 hours usage) < Nexus One (3 hours usage) < Z10 (3.5 hours usage)*
*Usage hours = screen time (50% mobile network, 50% wifi, approximately), my usage pattern is quite regular
Bugs:
I would never expect a new OS to be bug free, during the past month I have experienced a number of bugs, notably:
1. IKEv2 VPN connection refuses to connect when using Authentication ID type IPv4 (workaround is to use Email authentication)
2. I keep getting notifications to upgrade certain apps, when they are already up-to-date.
3. Occasionally Hub stops synchronizing all accounts, I have reboot it to resolve the problem
Misc:
1. Some people experienced higher than normal mobile data usage, but I personally have not had issue with mobile data, the usage is on par with my previous Android phones.
2. Some people said "Other data" uses lot of internal storage space. I have 50+ apps installed and "Other data" uses 5.5 GB. When I first got the phone, "Other data" used around 4.4 GB.
