Both devices has its issues. If you are happy with N770 then keep it and wait. I am using both and sometimes I prefer N770 over N800. N800 is better for web browsing since it is faster, Opera is newer and device has more RAM which is good for having more pages open. ALso N800 is better for media since you can fit more of them to SD card(s) and USB transfer speed is much faster. Otherwise N770 is good enough. Hardcover is great, buttons are better, it feels better in hand and the touchscreen is more accurate and display blinks and flickers less on lowest brightness. Basically I am leaving N800 at home for my family to use and carry N770 everywhere with me. And even at home I mostly stick to my N770 and use N800 when N770 runs out of battery or I want to do some more web browsing or something else where speed matters. So yes, N800 _is_ better but if you are happy with N770 stick with it, there may be things that you will miss when upgrading to N800. However the truth is that things will improve with N800 in future but N770's best future is now or is already over.
