So here is my experience with using this rom extensively over the last 48 hours:
I did a fresh install. The install went smooth. However I was not able to connect to wifi on first boot. I flashed Rohan's 1.5 mod, swiped cache and rebooted. Connected to wifi and the setup went well. The default trebuchet launcher does not support scrolling in my Executive Assistant app and neither does Apex. So I replaced it with ADW Ex. ADW started to act weird with widgets being lost and slowdowns. I replaced ADW Ex with Go launcher HD. I found it behaving better than ADW.
Wifi was behaving well even after multiple reboots. Before going to bed, I booted into WebOS and kept it charging on Touchstone. Today morning, I booted back into Cornerstone, but now wifi would not connect despite multiple reboots.
I had to make the TP forget my wifi, flash Rohan's mod again, wipe cache and reboot to connect to wifi. I am finding that I have to do this now after every reboot to connect to wifi.
