Modernizing vs. remaining cheap

These two options are mutually exclusive. Due to aging grey cells I lost my paper address book with all my addresses and phone numbers. Due to aging plastic and technology, my antique pda which was really just a cheap electronic calendar and address book (and was a gift!) went kerplouie before I lost the paper address book. So now I have the option of getting a new electronic pda/cell phone/internet access or just using an old fashioned paper address book. The problem is, because of my aging grey cells, I need to carry my electronic calendar - actually, my combined electronic calendar from office and home, along with my address book and perhaps have e-mail access to home while I am out. The problem is, of course this costs more money than I ever wanted to spend. Furthermore, the problem is I just got a new cell phone at work, so I can't ask for a new cell phone with pda etc. I don't want to pay for a plan for my OWN cell phone. So I have a conundrum. What shall I do? Will I give in to the modernizing pressure or remain cheap while my salary is lowered in this dreadful economy. Stay tuned is all I can say.
