I don't see anyone with notebooks out in public anymore.
You must not go far. I always see 5x more notebooks on planes than tablets.
The price, mobility, connectivity, UI, battery life and display of a tablet makes it supreme. The majority knows that. And anyone else is just niche.
I'm not sure you know what "majority" means. $699 for a tablet is better than a $300 notebook...how?
UI? You mean limited apps based around a kindergarten interface? Yeah, that's great for playing Bejeweled. Try running Logic Pro on a tablet....
Battery Life? That depends entirely on the notebook in question. You can easily change batteries on many notebooks (including my '08 Macbook Pro). You're SOL of if you run out of power on a plane with an iPad or even a newer Macbook.
I don't even know what you mean by
connectivity seeing my notebooks have Ethernet, Firewire and USB in addition to WiFi and Bluetooth plus a dedicated Microphone port. With my portable FW Audio interface, I have Pro Mic, Analog, Digital, Guitar and Midi interfaces available as well (you know for that portable studio I mentioned earlier). Exactly how is NOT having those options superior in connectivity???
Btw if computers from the 90ies can run MS office than tablets from today will run circles around it. Hook it up to a BT keyboard and you are good to go.
Microsoft Office is an odd comparison given how much it's changed over the years and the fact that it's not available for the iPad and even when it is, it won't have as many features (true of most tablet apps). The idea that a tablet from today can run circles around a 1990s computer is well...obvious, but how does that make it superior to a notebook today? An A6 won't come close to an i3, let alone a Quad i7.
If you're happy with tablets, great. Personally, the only use I have for them is as a remote and coffee table internet/mail checker in my home theater room. I'd rather use an iPod Touch or iPhone for sheer portability (i.e. it fits in my pocket) and I fail to see how having to carry a BT keyboard along PLUS a tablet is a superior setup to a notebook with a folding lid (i.e. I could carry the notebook by itself if I had to; the tablet + keyboard instantly necessitates a carrying case of some kind plus even if they were magnetic or something, you now have the same basic shape as a notebook, so...what's the point? Hence, I don't "get" tablets at all when you could have a notebook that isn't much bigger and has way more usability for a very similar price (the appeal of Netbooks was that they cost almost nothing and so for just e-mail, internet and office stuff you didn't have to worry about taking them on trips, etc.). I got my Netbook for the price of a freaking Kindle for goodness sake and it runs the full version of Snow Leopard just fine.
