I saw the bandwagon, it circled my block a couple of times while I toyed with the idea of hopping on, but finally let it pass.

I read the Twilight Saga. It took me two and a half weeks. In all fairness, the first three books took me a week, and the final one was the last week and a half.
I'll break it down a wee bit:
Twilight: so-so. Lots of brooding, lots of whining, lots of swooning. Some story. Definitely an easy read. By the end though, I was interested and wanted to keep going to book two.
New Moon: also lots of brooding, quite a lot of whining, and some swooning. Mostly I just found myself tearing through it to get to the end and the exciting bits. I like Jacob.
Eclipse: Not so much whining. Lots of brooding though. Jacob changed quite a lot...can't say as I liked him much anymore. This was definitely my favorite of the series though.
Breaking Dawn: ...just plain weird. I didn't like it. The characters seemed to have a totally different voice and like all of a sudden Stephanie Meyer didn't have to hold on to any shred of realism anymore and just went hog wild with mystical powers and bizarre events. I'm really not sure how they'll make it into a movie without it being totally grotesque and creepy.

All of that being said, I liked the Twilight movie, and I really enjoyed New Moon the movie (I'm fairly sure I'm branding myself as some sort of creepy perv by saying that Jacob is daaaaaaamn fine! He-llo!).
For your reading enjoyment, check out this blog entry I found online: "Reasons Why Twilight the Movie May Be Better Than The Book".
Points 3, 5, 11, 22, and 27 really hit home for me.

But, as my dear friend Mare said when we were discussing the first two books "Imagine if we'd been reading these ten or fifteen years ago! I'd have my bedroom plastered with Twilight posters!" And I concur.
