LAPTOP i7

ASUS Taichi21-DH71 11.6" Touchscreen Convertible Ultrabook Review At about six weeks in, I have mixed feelings about the Taichi. It is drop-dead gorgeous, slim and well put together. Both displays work well. It is light and well balanced enough to use as a tablet and is a wonderful travel companion -- better than a laptop or a tablet as it fuflfills both missions.

Mine came with a case, stylus, cleaning cloths, along with an inner case holding network and VGA dongles.
The issue, as the computer press reported, ASUS Taichi21-DH71 is that it is not a touchscreen laptop--to save thickness or cost, or perhaps battery life, the inner screen is not touch controlled and this forces you into using Windows 8 in a non touch screen environment - which is less than ideal. Loading Classic Shell is helpful, but I would have preferred it if Windows 8 had been designed to provide a Windows 7 experience when installed on a non-touch enabled device. I bought a Logitech 650 touchpad to use with the laptop side, but that is not a real solution.

ASUS Taichi21-DH71 I find that I am using the tablet side more, and enjoy the split virtual keyboard. The stylus also works well.
Wireless performance is very good, unlike the Transformer Prime. While boot time is pretty quick, WIndows 8 apps and some programs take a long time to load. This could be due to the limited RAM, I am used to machines I build with 16GB of RAM.

I have not blown out the ASUS partition and bloatware, which many reviewers recommend. I am not certain whether I could recover the programs if I change my mind-there is no rescue disk so I will be making a disk image when I get it set up to my liking and may try a re-install of Windows 8.

I have the variant with the Core I7 and 256GB SSD. ASUS Taichi21-DH71 The Core I7 is a battery hog-I get only 4 hours before plug-in. It gets slighly warm, but nowhere near as hot as my last tablet pc, the HP TM2 Touchsmart.
I picked this over the Yoga and the Dell XPS 12, and I do not regret my choice, but I wish both screens were touch enabled. If you are considering this I recommend you try to get your hands on first to see if its for you.
