If it's just phone calls that you care about, then every sin¬gle phone performs those tasks just fine. However, if you intend to download and run applications on your hand held PDA or phone, then you need a good processor and decent memory. Many phones today are capable of running streaming videos. These days, there is free software developed to run videos encoded using DivX and also those from You tube on a phone.

Performance only matters in PDA-phones, where multiple applications run side by side. Generally, phones come with 200-MHz processors and they're good enough for most applications. Winq.ows Mobile 5 generally runs smoothly on a 200-MHz ARM processor, but the same cannot be said of a phone running Windows Mobile 6 with a few. customised applications. Advancements in processor technolo¬gy have shrunk sizes even further. Intel's Atom is a new low power mobile processor announced recently, and is bound to take performance to new levels when they release.
