I can hold it with one hand comfortably, I think Apple was paying for bad reviews - so they had to find something to complain about.
Oh, and on the power thing, I've been running mine on battery since 10 this morning - normal business use. It is 5:30 now, and still has 66% battery left. Sure, if you leave it on and run it constantly, it will run down in 4-5 hours, but if you use it like a normal person (walking away, coming back to it), it lasts all day on battery.
No offense but that is the equivalent of saying my car will go weeks on a tank of gas because I only get in in a couple times a day. Four to five hours of intermittent use is what it is, whether it is spread across a day or a week or used in one shot. Try to use it constantly for a day and sit someone else down with a Lenovo Yoga and see who can work longer. Alternatively, get on a cross country plane with connections, get hung up in a lousy airport with only a handful of outlets and a plane full of people fighting over them, and try to get a full day of work done because that is what your boss needs. My Asus or Toshiba laptops with I5 and I7 processors will last the day and have some charge left over, so will the previous HP I5. My Surface RT will do just about as well. The same is true of some of the competing touch products. BTW, that is just one scenario of many that matter to people. As an archaeologist working in environmental compliance, I would view Surface Pro as the perfect device, if I could use it for a day in the field. Lots of others also work in professions where a device is needed and a plug will not be found. People have adapted iPads and other tablets to the task to get things done, and while they work they are clunky and inefficient. In the comparison between inefficient and "it ran out of battery life half way through the day" inefficient will win every time. That is, of course, unless I want to get paid for four to five hours or my client thinks four to five hours is good enough - no, those are obviously not options in the real world. Some will use a competing tablet, most will use a long life laptop, and almost none will use a short battery life Surface Pro.
Simply put, four to five hours of battery life is terrible for a tablet or a well designed laptop; poor to bad in comparison to quality first generation Windows 8 tablets; and barely even competitive with the first generation of mediocre touch screen laptops. I can live with the weight - it is barely noticeable. The same goes for thickness. I can just about tolerate the heat but do view that as a significant design flaw. It is still more a nuisance though than anything else. The battery life, on the other hand, is an absolute fatal flaw. For me, if it cannot last a day, it is not worth having. It just will not be on my purchase list, or my list of recommended devices for others either with my employer or other companies. I will, however, continue to recommend Surface RT, Lenovo's hybrid options, and probably the new tablet series from HP.
