On the road its ok as a lifeline device, but no more useful than an iPhone. In bed, it's awkward and needs constant holding to watch something.
To be honest, the BEST thing I've found it useful for is cooking... It's small, relatively risk-free of getting water in it. And the backlight stays on perpetually when you're mid-recipe.
Beyond that, Safari mobile SUCKS. Not having extensions is excruciating.
It's the device I want to love, but it's sat on the shelf 98% of its life. Which is why I haven't updated it. And it's such a shame. I even bought a keyboard case for it, which is again basically pointless.
