I have a palm 3xe. It has made life a lot easier, and a lot less messy for me. I especially like the date book, I do a lot of lawns for neighbors of my customers while they are on vacation. they ask me in advance, I put them into date book, set an alarm, and don`t have to worry about keeping notes where I can see them for a month or month and a half. It goes off a few days before to remind me.The mileage program that i put on it has made keeping track of pers. and business miles a breeze. It is all seperated and calculated automaticly, just enter thre beg. and end miles and specify bus or personal.I downloaded a mulch calculator that has made the process of figuring mulch easier and less time consuming. You can link it with lawn monkey, and have seen where you can link it to quickbooks. The newer palm devices also have expansion slots to make them even more versitlie. I like gadets, so will probaly give this one to my wife so I can get a newer one.
