The manual is short but helpful and generally well-written. I didn't notice any errors and Insignia provided a short index. I'm glad Insignia included the Errata sheet, because it explained a few things that the manual glossed over or had changed since Insignia printed the manual. Probably the best thing that I can say about the manual was that I haven't looked at it until today, over a month after I installed AccessPC. I didn't run into anything strange or unpleasant while using AccessPC that required explanation from the manual.
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
