Fair enough. I disagree. It's a complete overhaul but most people, including myself, feel it's a far more complete and consistent operating system than Gingerbread. I do agree that it's a little slower - but the performance difference isn't substantial enough to mention under normal circumstances. Hopefully we'll get JB soon and it will improve on some of the flaws of ICS. Not holding my breath though.
On .215 my phone runs faster on STOCK that it did on ANY GB build, including the stuff that DT and other cooked up that was fast. Mick - your chances of getting a GB phone are near 0 as they should be ICS is a superior operating system, it ups the level of security, adds functionality, and I have yet to find a bug in the released version or .215. If you phone is giving you trouble, you need to wipe _EVERYTHING_. When you boot back up, do NOT restore from Google (uncheck the boxes) and then install the Apps you use. If you are blaming the OS because some of your apps don't work, that is the wrong thing to do, blame the developer for not updating it -- especially if you paid for the app.
I recommend that you update to .215 and root. ICS is a far superior OS to GB.
