Just how stubby ARE your fingers? j/k I've been using my convertible netbook for a year now, and I never had any problems with using Win7 and Ubuntu with only my fingers (actually, occasionally I tend to forget I even have a stylus since I only use it with MyPaint and for notes taking).
Getting a good onscreen keyboard on Ubuntu was a bit of a pain, but the one in Win7 works like a charm and, thanks to it being configurable, makes for a very nice finger experience.
If it wasn't for battery power (4 hours on medium brightness setting and the thing is dead as a dodo), it would even qualify as an iPad alternative, for the only reason it's thicker than the aforementioned is because it has the hardware keyboard attached. Which, btw, doubles as screen protection in my pocket.
And of course it has billions of "apps" to draw from, actually useful ones at that, not the hundredth [fart/vuvuzela/add other sound here] app and the thousandth [facebook/twitter/add other website that's natively supported by the various finger friendly web browsers on Win7] interface app.
(Sorry, ysss, you know I couldn't resist on the last part. It's just that, even during those times when the iPhone was my only mobile device apart from my old Asus tablet brick PC, I've never even felt remotely compelled to buy any of the apps from the app store. There's a couple of nice games out, but to be true, unlike a lot of people I never bought a mobile device for playing games - which admittedly might sound strange coming from someone who's addicted to playing Albion on the N900... )
