The i500 is my first Palm PDA so I was unsure of how I would like it. My preference is Windows based harware.
For me it is the perfect fit. I needed a small flip phone with an actual touch screen PDA so I had to try it. No other choices yet.

It holds my contacts and syncs easy and takes notes well and is a very good phone so my minimum requirements are fully met.

It also holds my sci-fi books and Bible easily. The readability is good.
The internet access is much better than I figured, actually usable.

It is not likely I will ever get a larger phone so something new would have to come along to get me to change.

For those who need SMS or extra toys then they will need one of the bigger alternatives but if your thinking about just a PDA and phone only then this is ideal.
