Hi Laurie,
Great to see another Albertan here!
Regarding your question about a smartphone, I have a Palm-based Treo 755 and love it. I have had various Treo's over the past 6 years, so I am rather biased. I really like the integration of the contact list with my phone, so it's easy to identify callers and also to make calls. My calendar comes up with any appointments for the day and I use the memo application for the seemingly endless passwords one must keep track of. I can also access my email, so it's handy if I am out running errands to see if a client has emailed me in case of anything urgent. I use text messaging quite often for friends and family and have used the camera on occasion. It is Bluetooth capable, which for me is a must in the car, I have occasionally used the video camera in it, it has GPS which I have never used and the MP3 player I used in my last Treo, but I now have an iPod, so I don't take advantage of that program. I can sync it with my laptop, which is a great timesaver if I am entering in a lot of dates into my calendar or any other extensive data and it is a good backup system.
It really is up to you whether you want to spend the additional money, but I would recommend it only if you think you are going to
really put it to use or you have a specific need for it. As a new VA, I would consider this more of a luxury item and personally would spend money on new software or a new program you would like to purchase that might better benefit your business. The new cell phones have a lot of the programs that the smartphones have now, which wasn't always the case.
Hope that helps and good luck!
