I am curious as to why you are avoiding certain issues with the 210. Why you failed to test the CF slot issue, in what you claim to be an in-depth review. What you don't have access to a CF memory card? And as far as the SDHC slot goes I would suggest that a "class" 6 card does not work at class 6 speeds. Indeed when one compares the two hundred series to say the X51v the older X51v has far superior memory access speeds than the two hundred series does.
As to the mini USB connection, my experience is different than yours. With every iPAQ 200 series device I have tried, the miniUSB connector is current limited by the iPAQ and not by the source. Plug in say the mini USB charger from my Universal and turn on both Bluetooth and Wi-Fi and the power LED goes out! Connect to an APC rechargeable battery and again the LED goes out.
Set the USB setting to slow and it is very easy to draw more power than the two hundred series will accept from the miniUSB port resulting in the battery being slowly discharged. IMHO "slow" is worthless.
You've painted a very rosy picture for the 200 series, and avoided acknowledging so much as one bug in the two hundred series. Granted if someone follows the links you've provided they will learn of them, but you bill this as an "in-depth review" and IMHO any such in depth review that fails to acknowledge so much as even one "bug" is far from in-depth. Indeed the simple fact that you've taken the time to point out "bugs" in other devices and acknowledge them may make one wonder...
