Thanks for all the useful info so far.

As is so often the case with me, I get excited about buying a gadget for a few days then I put my sensible head on and start questioning whether I actually need it!

I am only considering a WiFi model since I'm happy with my phone for checking emails, etc when on the go, and I'm not someone who updates Facebook every 5 minutes (more like twice a year). Therefore if I'm away from home it's likely to be in offline mode much of the time.

So I can see it would be useful to have SkySafari, etc with me in the field instead of books, and I can also imagine starting to read ebooks generally, but what else might I use it for to justify the expense? Or put another way - I can justify around $350 for casual use, which gets me a Galaxy Tab 10, or the new Galaxy Note 8, but I couldn't justify $600 for the new iPad Air unless I was going to make real use of it.
