For the Raspberry Pi the stick is super: + Short breaks and roofs unplugged accidentally during transport from + Flasch and therefore does not block the 2nd USB port on Raspi + Does not need too much current and can therefore be supplied with electricity from Raspi without powered USB hub + Plug & Play with newest Raspbian
For the PC, I'd rather not take because ... -langsam -Short Range -no jack for external antennas
Conclusion: For Raspi good and the price is right also. For the PC, I'd rather pick up the AWUS036H or AWUS036NHR with 9dbi antenna.
