If you think that the N95 is big, then the E90 won't be for you.
The N82 is just about the same size as the N73. Plus, it has a Xenon flash for dimly lit environments, better than that of a LED flash. However, I'm a little impresed with LED flash when I had my N73 and N95-1. The flash didn't over saturate pictures like the 6681/6682 used to. Some users have complained that the N82's body feels a bit plastic-ky because of it's glossy finish. I personally don't mind. But if picture taking is your main concern, then the N82 is for you.
The E65 is considered by some the cheap man's N95; some who can't really afford the N95's go for the E65. Of course the profile is slightly slimmer than that of the N95. It's a nice phone. If you're looking at that, you might as well also look at the N81.
I personally don't think that the N95 is bulky. Pictures of it are a little misleading. I mean, if you can afford the money for a N82, you might as well get the best all around multimedia phone that Nokia has to offer, one of the versions of the N95.
