After extensive research for this Sony decided. I do not regret it for a second. - Great performance in video and image processing - Almost silently, only faint fan noise at full load (3D real-time rendering) - The anti-reflective screen provides a fantastic Full HD image - Blu-ray playback smoothly and without much noise - The HDD 5400 is quiet and fast enough for me The built-in speakers are not top notch, I can get over - you can the sound analog, decouple optical or HDMI. The eSATA port controls my powered eSATA 2.5 "-HDD without any problems. Overall a great, yet portable device.
