Thanks for the suggestions.
I like the reminder idea in the phone.
I looked into Androids reminder few weeks ago.
Apparently it's a half baked solution. Like when you say "Remind me to call Brendon at noon". Once set, apparently its not easy to find it, and almost impossible to update it.

Does anyone use an Android app for reminders that's easy to review, edit and data syncs between devices? Again, I'm worry about loaning an item to someone for 6 months and upgrading or factory resetting the phone in 3 months, therefore losing all local information.
I like Outlook's tasks functions but don't use windows phone and I can't count on remembering to walk into the office after I loan an item to someone.
