[citation][nom]belardo[/nom]FAIL! Windows7 tablets have been around for about 2 years. They run the same software TODAY that Win8 tablets will run tomorrow.[/citation]
What you fail to realize is that win7 tablets do not sell because of 2 main factors:
1) The hardware is crap. I have what is apparently a $500 tablet (got mine for free, fun but long story). This thing had an Atom CPU, 1GB of ram, 160GB HDD, and 6 cell battery which made the form factor HUGE compared to everything else. Honestly I would never buy this product, and if I 'needed' a tablet PC I would only throw down $350 for it (heck my smaller, lighter, nearly as long battery life Acer was $300 over 2 years ago, all the tablet did was add a reversible hinge on the screen, and a touch input). Now after adding another GB of ram, and a bigger/faster HDD it is an OK machine, but still not worth the $500 retail price tag.
2) Windows 7 absolutely stinks on ice for touch screens. Windows 8 on a touch screen is not only 'better' than win7, it is almost ideal. Seriously, the touch on 7 was slow, inaccurate, and lacking in functionality such as multi-touch, and pressure sensitivity. Just by installing Win8 without the manufacturers drivers I gained multi touch (2 points), pressure sensitivity (at least enough to differentiate between a hover and a click), and excellent accuracy that goes for the center of the touch instead of the upper left corner of the touch. The difference between win8 on the netbook/tablet vs the PC was barely comparable. The PC ran well, but the interface was clunky (but much better on RP than CP or DP... actually it was acceptably useful in the latest build, a little more improvement and keys/mice will be 1st class citizens again). Meanwhile, the gutless netbook flew much faster on win8 than anything it previously had (win7, and various linux builds), and win8 was really made for touch. I think people will be pleasantly surprised.
Remember, MS knows that win7 tablets are not selling, that is WHY they made surface in the first place. Not to take over the market, but to get their partner manufacturer's to get their act together, and act as a benchmark for others to hit on performance per $. And I stand by what I have said before; companies WANT tablets to replace antiquated technology such as LRTs, and other annoying and dated logistical equipment. Seriously, use an LRT all day in a warehouse with all of it's weight, crap battery, tiny buttons, and esoteric interfaces, and tell me that you would not die for a tablet with an easy interface, USB scanner (attached to the case?), and connected to some form of database back end! It would be a life saver! and no more expensive than the LRT in the first place. The problem is that their infrastructure is all Windows based with SBS, or other server products, so Apple and Android products are simply not an option. Having a domain-able device, where you can lock down all the settings for business use, while having real connectivity (that Apple cannot provide) is something business wants... the rest of us consumer shmucks are merely an afterthought with the ARM version.
