The Spiro is a cute little phone. It is so small, it disappears in my clenched fist. It is also really lightweight, but despite of the lack of weight and heft, it does not feel too fragile. The slide-function is really solid as well, and very smooth. Features are similar to most of the other SE mobile phones out there, so anyone familiar with the SE setup would not be too lost with this phone. The music player is also really crisp and loud. The battery life? A few days at least. Also, it has the "conversation" feature that my previous C3 had, whereby your text messages are grouped/threaded like a conversation, IM-style.
However, the camera is very poor (2.0 MP max), and the phone memory is horrific for a phone in today's market, just 5MB. A micro-SD card is definitely necessary. There is only ONE game in the "Games" folder, and the themes are very basic and not very pretty. It is NOT a phone if you are looking for a lot, but for the price I got it for (roughly $50), it does its job (call and text message) very well.
A good solid budget phone. Pretty Spartan, but one of the prettier basic phones out there. Very good value for money, if you are not asking for too much.
