I see HDMI and in fact connect my Kindle Fire HD to a HDTV with HDMI but for VGA you may want to consider a netbook.
I'm thinking of a, preferably Android but not necessarily, Tablet for around $200. But I need to use it to give presentations on a regular projector, i.e. I have to choose a tablet that can:
1) Be connected to vga through some minimal and cheap adapters
2) Can render power point with a reasonable quality on the screen (at least not pixelized).
Is there any suggestions on Tablets that can do this in a pretty straightforward manner?
