Accessing web in what way? Reading a lot of articles, newspapers online etc? checking facebook, twitter and so on?
What do you mean by great camera? Do you want to have something that can replace a pocket cam or do you want just decent pics. Do you want autofocus btw?
Tell us a little more about the use, maybe also perhaps how much you want to spend on it and what you define about light weight? E.g the N8 has the best camera out there but weighs in at about 135 grams ( which I concider not uber light, but not too heavy either). The formfactor is a tad bulky, but it's nice to hold. Would a smartphone be overkill?
If you're going to browse the web a lot, I would recomment one of the phones with a bit bigger screen and also touchscreen for easy navigating within the browser. Do you think a N8 will be overkill? Only you can tell.
