Everyone has their opinion about what their laptop should be 10x better at. Few people stop to think about what they'd have to give up to get it. Laptops are the very essence of compromise in computing, a more interesting question is what can you throw out to get what you want.
Want better battery life? I hope you like carrying giant sacks of bricks.
Oh, so you actually want it more efficient? OK, stick in a crappy CPU and a ton less memory. And get rid of any radios for WiFi or 3G/LTE.
Want a bigger screen and/or higher pixel density? Hope you like halving your battery life, or just cutting the back-light to "barely readable".
Want a ton more fast storage? How much money are you willing to pony up for flash?
Of course, if your answer is "I want it bigger/faster/better without the compromise"... well then just wait. In case you haven't noticed, it's exactly what the industry has been doing. It's not like they're sitting on their hands.
