Yeah it just seems too large and impractical to replace a much lighter and more portable tablet like the iPad. That's probably why Microsoft is having a hard time selling these. It's priced like a Macbook Air but isn't as good a computer and is priced higher than the iPad, but is too heavy to be a real alternative. It seems they're stuck in a hard place right now. The Macbook Air 11 is already extremely light but is a full computer and similar in price. Were it in the $500-750 range, I think it would be far more valuable.
It's a good concept though and it might become lighter and more practical in the future I believe.
We all want things lighter. But the SP3 is the exact same weight as the first gen iPad, remember that device that you were all giddy over and all the Apple faithful ended up lining up for? The difference here is that it's a full computer. It's quite remarkable. 1.5 pounds without the keyboard. And with the keyboard about 2.4 pounds. A 13" MBA is 3 lbs. So let's cut the too heavy bit. Yes, it's heavier than an iPad Air. It's not as easy to toss around as an iPad Air. But what I love about it is how much bigger the screen is and it definitely serves the function of a tablet. Sitting at home on the couch, using it at the office in my chair...
