First of all let me thanks all for your responses.
I will do my best to explain why I like to use email
My tasks are really sacred territory for me, only projects, s/m and next actions goes there. I have a really paperless environment, I think I receive 5 or less pieces of paper per week. so it is too much work to create a paper tickler; but going back to the issue, Why email. I receive almost everything in email, Email will give me the advantage of automate the process, I will be able to set up thing in a way that tickler will be put in my inbox everyday without any special thing, no need to look in the folder, or anything. Maybe my situation is a little special in the sense of the amount of information I receive is all electronic, all that I want is that get to my inbox, that is the reason I am thinking on emails, if there is a way to mark (maybe flags, I have not try it, need to learn it, thanks for the tip) and email and desapear it from my inbox and get it back in there at a certain day (the tickler concept) I will not need email at all.
Also I do not like alarms, because I think they interupt my focus, the only thing I use alarms for is hardlandscape because they need to happen at certain time, otherwise, I avoid alarms.
I also consider the online reminder services, but I will love to have everything integrated in outlook, since will give me the search capability, and I will not need to depent on anything else.
To the answer of the Tablet, I am in love, for me the tablet is a laptop with ink capabilities, I am not interested in write in ink on outlook, or write memos, but I love the idea of receive documents, write my comments in ink and send those back. Also I like to be able to take notes, in the tablet and do not need to have paper around. But it is important, I am not using raw data in ink into my system, I process everything with the keyboard, it is more a laptop with ink than anything else. Also the capability to rotate the screen is fantastic. in regards of the tablet I will recomend check it. I am in love with mine.
