Yesterday i saw the news, Dell's Latitude E6510 and E6410 have been coming out.
Dell released 2 new business laptop in the first quarter of the year 2010.

don't install HP Wireless Assistant if you need it to configure wireless AP. because it will not do that work for you.
what it can do that i found from the help file is:
● Turn Bluetooth® On
● Turn Bluetooth® Off
● Turn WLAN On
● Turn WLAN Off
● Turn WWAN On
● Turn WWAN Off
● Turn On All Devices
● Turn Off All Devices
and check device status
i was looking for a wireless ap setting management tool because vista wireless tool is not as confortable as xp has. but HP Wireless Assistant does not meet my needs.
