I tried out the Touchpad at hhgregg and here was my experience.
The software is very beautiful and works very well. Nothing looks like an afterthought. Some places are choppy and laggy like opening apps(5-10 seconds sometimes) and multi-touch in the photo gallery. Some of the Android tablets I tested like the Galaxy Tab 10.1 and the Asus Transformer were much faster when moving through the OS and instant when opening apps. Even with multiple apps in the background. Also, I find that the accelerometer is much more sensitive on the Touchpad while the Android tablets were slower to rotate to the point of frustration.
The hardware on the Touchpad feels well built but isn't worth the 499 base price. The Galaxy Tab is much nicer and has a better feel and the Asus has a unique 2-tone copperish-brown and black look. Overall, the Asus has a more sophisticated and industrial design. I didn't get to test out the front camera on the TP because of the lack of a camera app and lack of internet. The cameras on the other two aren't very good but they are ok for being on a tablet. The TP has a very slippery back while the Asus has more grip than the other two.
The TP's price doesn't justify the speed and the features it comes with. It feels like just another tablet and there really is nothing compelling about it.
The Touchpad really is a disappointing tablet for me. It feels like Asus and Samsung took more care optimizing the software. The other tablets also feel better built and like the TP is just an iPad 1 with a front camera and is slightly thicker and heavier and much more powerful but slower at the same time.
Experience at hhgregg:
The store is brand new and the associates are very friendly and are actually WILLING to help. The good thing about this store is that the tablets are the first thing you see with the Touchpad being the first one in the row of tablets. Sadly, only 1 person was playing with it. The associates are informed but the one I was working with wasn't too informed. He was more impressed with the Android tablets than the TP and sadly, so was I. So I think this store has potential to sell the TP well. They said the Transformer is their best selling tablet so I don't see the TP coming to the top anytime soon.
