Well, after using his ROM for a few days, I decided it wasn't for me. It's a beautiful ROM and has a lot of nice options, but unfortunately I found that the following issues made it sub-par for daily use.
- Unusual occurences. Weird loading, pop-in of widgets. I found that for some reason the screen would basically rewrite itself entirely when I exited certain apps and went back to home, and I would have to wait for widgets to load. Sometimes my Beautiful Widgets would lose the skin because of this, which was relatively annoying. When going to certain websites, the browser would hard crash, not even a force close message, it would just shut down.
- Battery life. I didn't have the crazy cell standby issues that others had mentioned, but compared to other ESE53 ROMs, the battery life is definitely worse, which is a big turn off.
- Performance. It ran great at first (I reflashed it a few times) but after it's been going for a little while, speed drops and weird things (such as the widget problems) start happening all of the time. I could kill tasks to speed it up, but I don't like having to do that. I had it down to 3 home screens to conserve RAM, but it was still happening.
- Propensity for 1x. I don't know why this is, but at my house I'm usually at 3-4 bars of 3G all of the time. With Koush's ROM, I was getting 1x at least 50% of the time I was at home. That's a big deal breaker.
So anyways, it was fun to try, has potential, but it's not ready for daily use (IMO) just yet. And of course it's a bit of a pain to flash back and forth between Clockwork and SPRecovery all the time to use all of the other ROMs.
