Ever paid the exorbitant access charges for Internet use in a hotel, only to realize that the single-user login means you have to take turns using the Internet with your roommate? Enter Connectify, a free Windows 7 application that turns your Wi-Fi enabled laptop (or PC) into a wireless hotspot. I've personally been using this software since last year, not just to share Internet access with Wi-Fi centric devices such as my iPod Touch, but also as a means to save on roaming charges on my Wi-Fi enabled BlackBerry smartphone. What's more, Connectify allows you to connect your laptop to the Internet via Wi-Fi, and at the same time share the Internet access via Wi-Fi. Learn more here.
