Bluetooth or WiFi

[mendione]

Some points I have clear (not everything is lost in me), like:
- WiFi is more popular and populated that Bluetooth (BT),
- That WiFi is faster and energy eater that BT.

But I made my own choice in terms of which technology I have to buy, and I think it will be WiFi. The most important variable is the availability of spots to be able to connect my portable, and I can see that WiFi is like 100 times more populated in the world so far than BT.

The second variable is the compatibility with my portable which is: a Dell® Axim X5 Advanced with two (02) slots, one (01) for SD card (no SDIO) and one (01) for CF cards.

My questions basically are:

1. What I can do?,

2. Which WiFi card I have to buy?

3. Is my Dell® Axim X5 Advanced 100% compatible with WiFi technology?

Please be so kind to also answer this questions to my email: mendione@cantv.net and thank you so, so much in advanced.
