Absolutely, I've read all the great ones as well. Actually I haven't even seen a negative one yet.
I guess I'm mainly disappointed by the pricing, and not from an affordability perspective... More so by the fact that Microsoft wants to be competitive in the consumer market with these tablets, but they're almost aiming them toward the business market exclusively.
The reason I think this is because of what competitors are doing: the iPad for example is a $450 device with it's base 16 GB of storage and Wi-Fi. These prices go upward of $700 as you add in more storage and connectivity options. But they sell like hotcakes. But so does the iPhone, because people love Apple products and feel their quality construction and app ecosystem makes these products worth the royal price they're sold for.
But look at the iPad mini: where did it come from? It's branhcing off the innovation and thriving success of the cheaper Android tablets that are available, specifically the Nexus 7 with a 7" screen. The iPad mini is just under 8" and has a price tag of $329. Apple made the mini to stay competitive with the cheap effective alternatives available.
Microsoft on the other hand, choses to enter the fragmented tablet market late and launch their flagship Surface with a $499 base price tag on a brand new platform which doesn't support legacy apps (granted neither does Android or iOS) but it also only has 10 000 apps currently available, which don't include popular ones such as Instagram or Facebook.
Then there's the subject of availability: online or at Microsoft retail stores only. Fail. If there was a Microsoft store nearby, maybe I'd buy one.
Microsoft's got a long game ahead of them... As they did with WP7, which I am an avid supported of, and now have a WP8 handset.
