Since a cople of weeks I own a Raspberry Pi. It's a nice toy. On one SD I installed XBMC. The other one has Raspbian. It took some time for me to get the Realtek 8192 USB WLAN stick to work. Now everything works fine.
 
Unfortunately I just got a kernel panic when I restarted the Pi. It's because I unplugged the power cable to restart the Pi quickly. Until now that's the way I did it until now and it worked fine. Even this tiny raspberry should be shut down the controlled way. Actually this was no big deal to recover: I plugged the SD card into a crad reader, connected it on my linux labtop and ran fsck on both partitions. Then my Pi started successfully again.
