Moleskine Vertical Weekly planner (large size, hard cover) with the slight tweak of using the top half of the daily columns as my days, and the bottom half as my notes and lists area. This in effect creates a vertical week + notes format that is proving very useful for me.
Things I like about this planner (there's a lot!!):
1) I remember things visually, so I function best with a weekly days-as-columns format so I can see the layout of each day list-style and the entire week at once. After only one week with my Filofax 2 Days Per Page format I lost track of what day of the week it was. I need the structure and linearity of seeing the week across the page. And the days as columns allows me to arrow over undone tasks to the next day instead of rewriting.
Moleskine weekly notebook, I had to cram my writing smaller into my day spaces while my writing in the lined Notes page was larger, causing me to pay more attention to my lists and less to my days. In my Trinote, I crammed my writing smaller into the list boxes, causing me to overlook those and pay more attention to my days. Having my writing the same size in both locations means I'm less likely to overlook anything.
3) The Mole wins the prize for forward planning. Seeing the entire week at once helps me plan the structure of my week, and turning the page to see subsequent weeks is very useful. But what makes this planner even more useful is the two-month spread in the monthly planning section. Seeing two months at a time makes planning the months and year so easy.
I write my weekly goals into the left column of my Notes area below my daily columns on the weekly page (below Monday) to keep my week's goals in view all week long.
5) Notes pages! This year's Moleskine weekly planner has NINE blank pages for notes at the back of the book. I haven't decided what I'm going to use all the notes pages for yet, but they are very nice to have. I'll use the 2-page spread directly after the end of the weekly section for forward planning 2012, since this year's Moleskine planners had to sacrifice the next year's calendars to make room for the (excellent and worth it) month view calendars. One of my complaints about my Trinote was that there was only one blank page for notes, so I didn't feel like there was enough space for creativity, listing goals, longer-term projects etc. In my Mole I have more freedom to do that. I also like having blank spaces like end pages and inside covers where I have taped in postcards of my favorite places in Scotland so I can look at them often.
6) Removable address booklet, which I use frequently. I have all my local contacts in it, business cards taped in, etc. I transferred my address booklet from last year's Moleskine so I didn't have to re-write anything. I saved my new address booklet so if we move this year I can use it to write in local contacts at my new location and swap out the booklets instead of having outdated information written permanently into my planner.
7) It's so portable! Even with all these features the book is only 5 x 8 1/2 inches and less than 1/2 inch thick, and weighs nearly nothing. I can take this with me absolutely everywhere in my bag and not notice the weight, unlike the size and weight of my Filofax or Trinote.
8) It fits in my cool and functional Rickshaw Bagworks Moleskine Folio!
Zero Messenger Bag which I take everywhere and holds all my stuff, so it's a matching set! (The light in this photo makes the purple look more blue than it really is.)
Like I said, there's a lot that I like about this planner! This is a real contender for Planner Of The Year 2011! In fact, I think this is the one to beat.
