I've been looking for an app that can sync with my Outlook for a long time and I decided to try out VCOrganizer Pro. Basically it's a standalone app that syncs with your MS Outlook tasks, notes, contacts and events which I use all day long. I have >2.000 contacts and with this app I have no problem in managing them. I am on the road for most of the day and it's handy to edit your calendar/tasks on the go, instead of remembering them until you are behind your PC at home. I never miss a task or appointment anymore, highly highly recommended!
Vecal Company is one of these developers that actually focus on programming instead of marketing, and I respect that a lot.
