I want a pocket-sized gadget with a non-terrible calendar system that will make noise at me to remind me of appointments and so on. My current cell phone has a calender with a UI so bad that using it is more trouble than it's worth. iPhones and Blackberries seem to have what I need, but they are rather expensive (especially once you consider the monthly plan, which is a lot more than I'm paying for my cell service now). An iPod touch might work, but I'm concerned about the price and the apparent lack of speakers loud enough to alert me of anything.
Does anyone have any tips? Or any idea of what I'm looking for?
