when i hear the notification, i just look at the phone (just like i do with my x). when it has been on vibrate, or if i havent had the phone on me, i just hit the lock button to look at the notification bar instead of looking for the light. it's not really too big of a deal.
picture quality is great. i have heard some claim it is oversaturated, but i think those people are trying to justify why their phone's screen is better. the display is amazing. and, for being an amoled, it is much better in the sun (than the DInc).
as far as speed goes, it's honestly a tossup. when i did browser comparisons, they literally were less than a second of difference between the time the link was clicked, and the time the page was fully loaded. sometimes the x won, sometimes the fascinate won. as far as launching apps, again, they were almost exactly the same. like i said before, when playing games, i experienced less lag with the fascinate. it wasnt a HUGE difference, but once in a while my x would experience a quick (half a second or less) lag, where i never saw it on the fascinate.
call quality was great. but, i live in denver where verizon has great coverage. i had the phone in the mountains with me a couple times, and there was nowhere i could use the x that i couldnt use the fascinate. in the month i've had the phone, i have not dropped a single call. there was a time or two i thought i did, but I had CS pull up my account to check, and it turned out it was on the other end.
as far as ram/internal/SD. yes/yes/yes. but, i honestly didnt notice the memory difference. i was a bit disappointed in the 2GB storage, but it still takes quite a few apps to fill that up. but, i know a lot of people will be running out of space.
