My PDA is indispensible. I use it for a contacts manager, a task manager, a calendar / scheduling tool for meeting's, a spreadsheet/word document reviewer, a remote email retriever/viewer, a storage device for MP3's/Jobsite pictures/jobsite videos, etc. I was very pessimistic about using a combo PDA/phone, didn't think that it would be that handy. I was wrong! Can't do work without it now - it probably saves me 1 hour a day just in not having to log onto a company computer for email. The Treo was the best in features model when I got it 6 months ago, so I am not sure if there is anything better yet. Two of my buddys told me this - and I find it true - the Treo is a crappy to ok camera, crappy video recorder, good phone (but nowhere near as nice as a high end stand alone cell phone), good to great contacts manager, fair to good MP3 player, but when you add them all up together in one piece of equipment, it becomes something you can't work/play without.
Want to impress someone? Sync your PDA to MS Outlook, setup your Contacts Manager, enter in a new contact, and put in info on them as you get it... I have a buddy of mine, Sr Project Manager at a GC outfit, he told me that his wife was expecting and their due date was 10/20/05. So up pops a reminder to check with this guy that I haven't talked to in six months, I call him, just to say congratulations and did you get my gift for the new addition... he really appreciated the personal touch. I get calls from him for business now.
On top of it, I can use it for things like Exbal, or with the GPS attachement for GPS/Roadmaps, for internet surfing (small screen but works in a pinch). I can install most any Palm program from literally thousands of existing Palm programs and there are so many people out there using them that there is something else always being written program wise that comes along and can be added to the unit - ala Exbal.
At $450 plus just to buy the phone and then a monthly $100 cell phone bill it hurts to get started.
I probably use 1200 to 1500 minutes of cell phone time a month on my personal phone, so take this into account. If you can live without a cell phone, then this thing is no better than the $170 PDA - and it has recurring monthly fees that a regular PDA won't have.
Not to be too long winded (I am known for this though) the GPS is pretty cool, it would be neat to see if this could be used in conjunction with Exbal for automatically inputing range conditions - elevation, distance from one point to another if you are preprogrammed for certain spots, etc.. I could see a Kestrel
unit being synced to a PDA for the same thing - weather, temp, humidity, wind speed, etc. for LRH use. If Exbal doesn't do this yet, I wouldn't be surprised to see this available in the future. Are you listening, Kestrel/Palm/Exbal? Back to the original question of the post - does anyone have a good bit of experience with a PDA and Exbal?
I can see a program that captures data from a Weather unit, then uses GPS for location to known coordinates (distance of shot - i.e. if you know that the Mouflan rams always sun themselves in the winter on the north face of yonder cliff, then program it into the PDA in the summer when you can walk to the spot - maybe useful, maybe better to use a rangefinder), then presto walla, out spits your data... don't know how far I am off here, it would be neat though.
