I actually woke up to several reviews this morning, and they all seem more positive, than negative. Over at NeoGAF, most of the members are surprised by the positive reviews. As usual, if you don't understand a device, than it's not for you. So many guys leave such negative comments, and they have no clue why a device like this would appeal to someone. Even if you don't look at this for gaming, it has kick-ass performance and best almost another tablet or smartphone around, and it's priced waaaayyyyy better.
I've been interested in getting a tablet for awhile, and what has always stopped me, was the lack of gaming controls. Although things like ICP, and other Bluetooth controllers exist, I'm more about the controls being included. So far the biggest negative I have seen for me would be the lack of a good way to hold the screen to use the onscreen keyboard.
I really think they should have allowed the screen to flip over on to the device, so that it could be held proper for screen press inputs. That would also be good for playing those android games that only work in portrait mode. When I use my DS/3DS sideways for portrait games, it's not to bad since both half's are the same overall shape and weight. It's like holding open a book. The reviews point out how heavy the control portion is, and this has to be a consideration when holding the Shield certain ways. I'm sure if this device sees decent sales, they will offer an improved design somewhere down the line.
Overall, it's looking nice. My main concerns right now would be overall controller support and games down the road. Nvidia isn't a big game player like Nintendo or Sony in regards to making games, but they have relationships with almost every game maker in the industry due to their standard business. So if anyone can make a device like this, and gain some decent long term standards and support, I think they can. Almost every ios and android game maker should see the value in having proper game controls for their games(if the device has physical controls or not), and this is a solid step in the right direction for an industry standard.
Now I just need to see some N64 and overall emu performance, and I should be getting one soon. All the reviews state how fast this thing runs, so I'm really looking forward to what can be done in regards to the devices emulation performance, it should be awesome.
