Excerpt: Not everyone wants an expensive smartphone, and the Nokia C5-04 caters to those who want the functionality of a smart phone without the expense. The C5-04 uses the Symbian operating system combined with a touch screen interface that works well. Hardware specifications are nothing great, but still respectable. The C5-04 uses a 600MHz processor and has 128 MB of RAM. This is good enough for most users who are not running ten applications at once.
