The real question is what do you do with a tablet? That's the same question that people who don't own an ipad has. What do I do with a tablet? I think what will happen is Microsoft trying to merge their laptops with a tablet.
I don't think it will work, at least not to the level of an iPad. It would be nice to have an all-in-one but if you look at history, this has never succeeded. Certain things are created to service a purpose.
If you look at the iPad, it is what it is - a luxury device complementing a laptop/desktop. If you try to make an iPad a laptop, you will not be happy. There's currently a huge compromise in power/performance battery consumption, weight, heat, and screen resolution. I don't think Microsoft has a clue to the needs of the many.
History has it Microsoft is just all about trying to follow what's hot. They never invented anything on their own. Look at MSN, MSN Search, MSN Live, Bing, ...every product this have is nearly a copy of someone else. They had the money at the time to squash out competition and monopolize their presence in the PC world. People are cheapskates. They love cheap everything. They refuse to pay for anything aesthetically pleasing because that would mean $$$. So every junk manufacturer comes out with PC junk and we have what we have now, a pile of PC crap. Microsoft is ubiquitous because of pirating. It's definitely not the retail price of their OS software.
Go to asia, look at the 99.9% of the population there including retail businesses. No one buys official license software. There are over 4 billions chinese/asian people. 99% of them don't pay for software. They would bootleg hardware like they do software if they could. It's all because it's just cheap PC junk.
BAck to the topic of Windows 8 tablets. Sure they are trying so hard to get into this new market that Apple is successful in. Unless you can magically replace your laptop with this windows 8 tablet, i don't see the point at all. It's just another iPad'esque copy but of course, it looks like crap and I don't see how it is intuitive with all the stupid cluttered tile BS.
I can clearly tell you Android tablets running ICS are better laid out than this metro crap. There will be many who will claim victory but those are the same people that bought the RIM playbook, the same ones who buy lenovo laptops (which are the ugliest and crappiest laptops on the planet). I don't care for any windows products either so this tablet will not interest me at all. All i want to do is sit back in my chaise lounger and hold my ipad and enjoy the retina graphics.
I have my mbp for everything else. I am so integrated into the apple ecosystem now (sans my cellphone which is a samsung), I am nearly complete. Just ask yourself the real question: what can this windows 8 tablet do that your laptop can't do better? What can it do that an ipad can't do? 1366x768 resolution is 2008 technology. There's nothing amazing about this lenovo windows 8 tablet.
