I just ordered mine today (arriving tomorrow) and I forgot that MS decided to screw WP7 users over with the hidden microSD card. While I am no stranger to opening up devices to get things done this is something that should be part of future WP7 devices, or this will likely be my last one.
Still after having Palm OS, PPC, BlackBerry, Android and iOS (skipped WebOS) this will be my first WP7 device. Based on the over all reviews of the OS, and the upcoming Mango update I thought I would give it a try. Hopefully this won't let me down.
