Watching movies on the train is hard on 4.x” screen which N810 has (I used it once for that) and I prefer to not imagine how will it look on N900 and it’s 3.5″. But I can imagine taking Touchbook from backpack and watch movie on it.

Power usage is my main reason to consider Touchbook — it has to have 10-15 hours on one charge (there are two batteries in device). This will make it a nice companion for conferences — take it from charger in the morning, use during day, plug charger in the evening.

1) It fits in your pocket – carrying a netbook requires a bag, I go lots of places without a bag.

2) The power usage means you can treat it like a mobile phone (i.e. leave it on all the time, charge it when it needs it).

I can give heaps of examples of things that are possible on a tablet that you can’t/wouldn’t do on a netbook. Instead, I’ll tell you 3 anecdotes from today – these aren’t the killer apps, but hopefully they give you a taste for how it is in a different class:

• On my way there, I forgot what the address was, so without slowing down, I quickly checked.

• I was walking home in the rain, as I walked under a covered area, I pulled it out and resumed playback of a podcast I was listening to – without slowing down, and without it getting wet.

• Once I was home, I left it somewhere, since it is always on, it connected to my wifi automatically, and I transferred some movies to it, so I could watch them on the train tomorrow, all without having to touch it.

Yes, I’m sure netbooks have their place, but they just wouldn’t substitute for an internet tablet for those three things.
