Terapixel Night Sky Microsoft's Terapixel project, part of Microsoft Research, stitched together more than 1,700 pairs of photographic plates from two powerful telescopes to create the clearest, largest night sky map yet. Microsoft

Ipad gets my nod as better E-reader

Harry Clarke - August 2, 2010 - 4:05pm

I’ve previously reported on my Kindle and Ipad purchases.  Both are great technology so I am happy to praise both. Though I must say that – given its connectability to any part of the WEB – the range of things you can do with Ipad is much greater. And OK, this is fairly bourgeois, but the colour screen is a winner.   Ipad is a fair bit more expensive than Kindle so you are paying for the extra capability – if you only wanted an E-reader Kindle might hacve an edge.  The only real advantage of the Kindle for me was access to the enormous Amazon.com E-bookshop.  But now that is gone too since Kindle provide an APP for Ipad that allows download and purchasing items direct from Amazon.com.  I did this over the weekend and I think its navifgation potential within a document is better than Kindle.
