Review: Tadellos. - Er funktioniert einwandfrei, und wenn jemand das zweizeilige Display im klassischen Stil schätzt ist dieser Rechner eine gute Wahl. Man merkt aber schon anhand des Funktionsumfangs dass er schon in die Jahre gekommen ist und definitiv ein Design der 90er ist. Da ich aber Rechner sammle bin ich froh einen neuen abgestaubt zu haben.
Review: Nice
