Some more impressions:
- Video payback is very good on TV screen. But it needs to be a high-res video (640x480 at least). 320x240 looks noticably worse.
- Video recording is also good. The best quality on recording settings is 2500 kb/s. 1500 kb/s is considered a low quality The video recordig format is MPEG4.
Ultimately, this device is NOT a replacement for Zaurus, especialy after C-series. It's a different kind of device. Its PIM capabilities are poor. The screen is too low res to be used for web surfing or comfortable reading. Built-in WiFi sems to be useless with such a screen. Qtopia apps run slow. Memory is 64 Mb, but 40 Mb are used even when no applications are running.
But, it's an excellent media player. 30 Gb of internal storage, USB 2.0, TV in/out, video recording and playback - all this make it a great portable video player. Audio playback quality is also good - I didn't notice a difference from Zaurus when using good earphones.
