Well Samsung works for me. I had to root GS2 for regional font support and print screen. In GNote, I ran stock unrooted for 6 months as all that I needed were already there. Then I started exploring and flashed several ROMs. Some which are closest to Nexus version have everything in white background (eye straining). Some do not support SPen. Some had more annoying bugs than Samsung stock. So finally back to stock TW and TW is blessing. If I buy Galaxy Nexus, I will want to flash TW. When OS starts to reach maturity, having latest OS is not always required on the first day. For example - we can almost run everything in Windows XP, the same has started to hold true in Android too. And SPen is blessing, it has saved me borrowing pen from waiter and draw quick diagrams on tissue paper dozen times.
