This is the best handheld PC that I have ever owned. I use this for work and my productivity has greatly increased. It came already updated. I put in my 4GB SDHC card and the PDA read it without an issue. The wireless is also very good. You may read comments from other sites about this, but I think that the updates made to this model have improved the wireless. The VPN worked without a hitch. I can access my work e-mail through the VPN without an issue. I also downloaded all of my contacts and meetings. Office mobile is excellent. Now, I can take my documents wherever I go, and into meetings without my laptop. The sound for MP3s is quite good as well. Overall, this handheld PC has essentials for the business professional. The product works smoothly and quickly. I have not had any issues and I am very happy with it.
