Currently I am running the stock 2.2 w/ Sense (S-off) with LauncherPro and really, really like it. In particular the swipe actions with the dock icons. I can't think of anything that I want to do with the phone, perhaps because I don't know what's out there. I do have Wireless Tethering set up which is cool. But I was thinking more along the lines of, "what does a custom ROM and/or Kernel offer that I can't do right now?" The only thing I was thinking about was throttling the CPU with SetCPU - leave it normal for use (perhaps underclock a little?) but downthrottle for sleep/idle to increase battery life. I see no reason to overclock since everything is extremely snappy as-is. Can I use SetCPU on the stock, rooted 2.2 w/ Sense? Or do I need to install a custom kernel for that? Speaking of kernels, is the stock kernel "part" of the ROM? Is it backed up automatically when doing a nandroid backup? I have messed around with downloading/installing ROMs and kernels and extras with ROM Manager (tried Virtuous with INC-RED theme) and wasn't crazy about it (missed my LauncherPro). I had installed the custom kernel with that, but restored everything from my nandroid backup. Do I now have the stock kernel loaded?
