Summary: I'm a full time student and I bought this PDA a year ago. It's been so nice for me to have. The WiFi is perfect. I can almost always get connected. The SD expansion slot is really nice for adding books etc (I have a few different versions of the Bible with commentaries for super fast and easy access). I love the note pad, I can write up things quickly or 'type' them in. Its also SO nice to use the Microsoft Outlook to update my contacts and calendar.
Summary: I would not recommend using the Windows Mobile's Media Player on the IPAQ for playing videos. I would recommend downloading a free version of TCPMP DIVX player for the Pocket PC at the following location. TCPMP is a far superior video player than the WM Media Player. You will not have the buffering problems that the WM Media Player has. Your videos will play smoothly without interruptions. It also plays a wider range of video format than the WM Media Player.
