"Re: I still don't know" - I know
I take it that "asdf" is US based, ignorant about prices in Europe, and UK IPTV.
The main initial reason that tablet sales are lower in the UK, compared to the USA, is because of the rip-off prices that the big brand names charge - currently of the order of 60% more than the US price. There is no justification. The tablets are manufactured in the Far East, and key components such as the ARM CPU and MALI GPU are actually UK IP.
Subsidiary to that, there are good reasons to have waited for Android-4 to be released, that would make the multi-core Android tablets significantly better. A $100 tablet with Android-4 and an ARM Cortex A8 1.2GHz CPU, plus dual-MALI GPU, overall performs better than all iPads except the latest one, and is also a match for the Samsung and Motorola Tegra-2 tablets.
Sold under various names, these are not over-priced by all retailers. For example, the Kindle Fire is even a very poor buy for the US customer, compared to the $100 tablet above.
I get instant-on, no fan blowing, on my netbook - it's a Dell 910 with SSD. It does everything an iOS or Android tablet can do, and very much more as well, except I use a mouse with my arm resting on the arm of the chair instead of having to move over the touch screen. No strain at all. Where others complain about using a larger tablet by saying there is strain over long use.
What makes a netbook better than a tablet for the UK user is the fact that it has its own keyboard and stands without additional equipment or holding. So it can sit on the arm of my chair without having to hold it., often using it as if a portable TV, that can easily moved around the house.
In the UK the BBC iPlayer is excellent for on demand TV, archived and live streams. Other IPTV is available, not quite as good as the BBC.
Almost all netbooks probably use intelligent Li-ION battery management, exactly the same as tablets. So the following is a fatuous generalisation: "You can set the thing down for days instead of hours and not worry about the battery being dead unlike most netbooks." When a Li-ION battery goes dead it usually cannot be recharged, the battery management system prevents it, and it doesn't matter if it is in a tablet or netbook.
Uses for a tablet - they seem to be useful for media presenters - quick access to lots of notes.
Younger kids love them of course, as a new kind of games device for TempeRun etc ,probably until they grow bored.
Teenagers prefer their laptops, proper keyboards for the IM/social networks, games music and school course work that you simply cannot directly do on a tablet.
The only tablet usage reason I can identify is as a third-screen device - left on monitoring Twitter when I'm using a netbook/laptop/desktop. I don't Tweet, but follow many people who use Twitter to send URLs to articles and video of interest. I used to do this with an additional screen set-up on the netbook - not entirely satisfactory given the crippling of netbook specifications to satisfy Microsoft.
