My first camera phone was a Sony Ericsson years ago. It took terrible photos, but it was such a novelty to take photos with a telephone! Now my iPhone is my only camera. Well, apart from the camera on my Galaxy Tab. And oh yes, there’s even a video camera on my iPod Nano! But I no longer have a dedicated camera. The only thing I miss is an optical zoom.

PS …And oh, I forgot. There’s a camera in my MacBook too. Come to think of it, I have cameras everywhere – except in a camera.

I think you know about Magic Brush and Canvas. Autodesk Sketchbook Mobile is newer to Android and best of all so far – so I think anyway. See a few Android / iPad comparisons at http//:www.OWLER.com/-blog.

I registered ages ago, am doing a joint presentation with Julia but don’t know anything about tickets. Where do I find out if I need one, and if I do, where do I get it?

You’re not alone! I’m a mini-gadget freak and I can already feel my fingers itching… I wonder if the new Nano will take apps. For me, the iPad, though nice to use, is just too big and heavy.

I’m puzzled, because Vellum on my iPad is unusable. The screen is just streaky noise. Vellum is even pretty sticky on my iPhone (4) these days.

Thank you. Fascinating article! Interesting that Hockney paints such huge canvases and then sends tiny pictures from his iphone. I tweeted the link.

WOW David! My ambitions exactly.

I spent hours hunting for a reasonable price for the visit to NY. I had hoped to use Air Miles, but haven’t got enough. In the end I managed a custom package deal with a big firm here in the UK, Thomas Cook. I was really chuffed to discover it ended up as HALF the price I would have paid for hotel and flight separately!

I am staying at Holiday Inn SoHo. Unoriginal perhaps and still a bit pricey, but at least it’s one of the hotels recommended by the NYU site. I would rather have had something cheaper and more exotic, but I’m no student any more, and I reckoned a big chain would be more reliable. I’m only staying 3 nights, Fri, Sat, Sun.

I do recommend looking around for a package, as you can save quite a bit.

There are some colour apps you could look at: – Mill Colour, Peppermint and ColorSplash. I have Mill Colour and Peppermint, but haven’t used either yet so can’t tell you anything about them. Truth to tell I found them a bit daunting. You might like to explore them though.
