If the WiFi in your office is quite weak or non-existent and if you don't wanna use your smartphone's data plan bandwidth for streaming music, checking your personal mails, sync-ing your online calendar etc, why don't you convert your laptop to a high-speed WiFi hot-spot for free? You can connect your iPhone, iPod Touch, Android Phone all to your laptop (connected to a LAN Ethernet connection) using free software like these:
2. Virtual Router
3. Virtual Access Point
I tried the first two; Virtual Router, the 2nd one, didn't work for me. Connectifi worked quite well. Now I have high-speed internet on my androd phone for free. Kudos to the developers.
