My fave ipad app so far...

[ffutures]

Although I'll probably never have a huge amount of use for it, my favourite app so far (and I've even paid £1.49 for it) is Measures HD, which uses the built-in sensors etc. for various possibly useful purposes

Tesla meter - fairly sensitive magnetic field meter
Decibel meter - noise level with graph
Big compass with GPS latitude and longitude
Protractor - not sure what I will use it for
Ruler - ditto
level gauge
Spirit level
Plumb bob
Seismograph - yes, really, very sensitive too
Stop watch
Timers
Metronome

I'm reasonably sure I'll never need most of these functions, but it does seem amazingly cool.

I really didn't expect to like the thing as much as I do - it really is quite different from other computers, and while I suspect it will never be hugely productive for me it has some interesting possibilities.

Yes, there are a lot of things you can't do on a tablet. Like typing, they're hopeless at anything that involves more than a few keystrokes. But still very nice toys none the less.

I use mine mostly for comics.
