HP IPAQ hw6515 and Wi-Fi question

[maidstoneman30s]

Hi there all,
A few weeks ago I was in Dixons Heathrow, having a look at the IPAQ hw6515.
On the description it said it had Wi-Fi, which is of importance to me and my colleagues.
Having been on the hp website tonight, it does NOT state Wi-Fi, but Edge.

I do not know anything about EDGE, and wondered if EDGE will work with our
Wireless Router Netgear DG624 in the office.

Can anyone help in this matter.

Also, what would your reccommendations be for the following PDA.

PDA and MOBILE phone in one
Wi-Fi
Bluetooth
Windows OS with Excel / PDF
Aditional Memorys slot ie SD card or other type to store pdfs and Excel's

Many thanks for your help.

The above are the most important to use, and anything above that is a bonus
