You are luchy I happen to know it well. PDA phone means a cellphone with PDA function. As to PDA, it is a abbreviation of " personal digital asstance". You can reagard it as a little computer in the hand. PDA fields mainly contains two operation system: plam and windows. At present, windowns system is more prevalent than plam. PDA phone offer strong multiple media function such as reading E books, playing videos, reading all kind of office fiels, which almost can do whatever the computer can, besides the phone function. The disadvantages of PDA is its short battery time, and complexity. If you don't have special demand for your cellphone,what you need is just making a call or texting a message, I recommend you the regular feature phone.
