I have the following four options for my first entry level PDA. I need GPS, WiFi, Edge, Touchscreen, Windows Mobile 6 as a must. Options that I have shortlisted are:

1. Sony Ericsson P1i @ Rs. 17500 (Indian Rupees) - I know it's a Symbian but is highly recommended.

2. HTC Touch @ Rs. 13500 (Indian Rupees)

3. ASUS P527 @ Rs. 14500 (Indian Rupees)

4. ASUS P320 @ Rs. 12500 (Indian Rupees)

Please help me make the right choice, by suggesting and sharing your experiences. Any other suggestions in a similar price range is also welcome. Thanks.....
