upgrading via PCC is as simple as connecting the phone to PC via USB. A better way to upgrade is using Sony Update Service (SUS).
There are some bugs in ICS, but they are mostly solved by a settings reset or worst come worst a repair.
Charge is used faster, there seems to be some notification sound problems and some wifi issues. I am not personally facing any issue but these are the common ones in the forum.
I've found improved battery life in ICS, my notifications for email, texts, whatever come through fine, and Wi-Fi issues can be solved sometimes by specifying an IP address manually for WPA(2)/PSK networks, then enabling DHCP.
This is a common fault in most Android builds, including Jelly Bean on the Nexus 7.
