The highest resolution of the Nano Go 2 is nHD (640x360). That's 78% less resolution than the most common native projector resolution of WXGA (1280x800).
Other data projectors that have a resolution of nHD (640x360) which you might want to also look at include the PPX2330 (£189), or the PPX2340/F7 both from Philips or the XXODD Nano Go 1 which have a better Kagoo Rating™.
If the resolution of this multimedia projector is not high enough for you then you might want to also look at the MobileCinema i50D (VGA (640x480 and higher rated) and higher rated), the MobileCinema A50P (£175.37) (VGA (640x480 and higher rated) and higher rated), or the PocketCinema V60 (£230.01) (VGA (640x480 and higher rated) and higher rated) all from Aiptek.
A nHD (640x360) native projector resolution is actually the worst resolution across all similar spec projectors that have been on the market for a comparable time to the Nano Go 2.
A WUXGA (1920x1200) native projector resolution is the best resolution amongst similar types of multimedia projector.
