I've been using the Moleskine Cahier XL for 3 or 4 years now, and I love them. Soft cover is flexible for folding back, they're lightweight, a comfortable size for carrying with my laptop, and hold up well. Each book is roughly 8 months of working life.

I don't use page numbers though - I do date every single entry.
