I am old school when it comes to agendas/calendars. I don't use my outlook calendar or my Blackberry calendar or my mac calendar. I use a traditional agenda book still. For work I use the cheezy work logoed one but for my personal life, I use this beautiful Kate Spade agenda. Here is what I like best about it.
1. The shape, it is a square, and squares are cool, unless you act like a square and you probably aren't if you are reading this.
2. It's pretty to look at and to touch. I like when things feel as nice as they look. This agenda is both.
3. The inside pages have enough space to write and a whole week on a 2 page spread.
The best part about agendas is that you can flip thru the pages and see all the fun stuff, crappy stuff and forced stuff you did all year long. It's like a diary, but not. Because it's an agenda and it says so on the front.
I don't even know if they still sell these, but if they do, they run approx $50
