Pros Full Windows 8.
Good battery life.
Includes adapters microUSB to USB and microHDMI to HDMI.
Cons Tablet has a single microUSB port that doubles as a charging port. You cannot charge while connected to a USB device or connect to a USB device while charging unless you are connected to the optional keyboard-dock, which has been discontinued!
Summary The bonehead charging/USB design from Microsoft and Lenovo overrides anything good about the tablet.
Pros GREAT PRICE ($349 for both tablet and keyboard dock), GREAT battery (with keyboard, 16 hours),and 2 USB 2.0 ports. ultra-thin too!
The regular price is $649 for just the tablet
Cons The keyboard takes a bit of time getting used to and the touchpad is bit to small. Does not come preloaded with office 2013 like some other tablets. Also it is a bit tricky to detach the tablet from the keyboard dock.
Pros Very light.
The ability to run my development programs such as sql server, visual studios and ms office.
Amazing battery life (with the keyboard).
2 full usb's in the keyboard accessory.
Cons The optional keyboard keys has so much flex that it makes it difficult to type.
The touch pad is just AWEFUL
Very cheaply made keyboard.
No back facing camera.
Summary I chose to the get the Lenovo over the HP Envy x2 because of 2 things. 1, it was readily available and on sale (bought at staples with keyboard dock for $599) and 2, I read that performance was marginally better than the HP Envy x2. There are a few things that make me regret the purchase, but love the convenience. The keyboard dock is excellent in concept, but the touch pad is very very twitchy. I have tried everything to attempt to tweak the touch pad, but it is still a very poor experience. The keyboard flex is also so bad that it makes it difficult when I type. I type a lot, and that experience is very bad. However, I do have a Bluetooth mouse and a Microsoft arc keyboard that are awesome, but when using it as a laptop that is one of the worst parts. now for the good.
The performance of this device is awesome. I have a very efficient laptop and all I wanted was something that would be able to run some of my development software, office products, read my programming reference books and play music and then last for more than 8 hours. Well, this fits the bill and plying xbox live games is a plus, but not a necessity. Oh battery life is ridiculous with the added keyboard, I mean we are talking cell phone battery life at 12 hours (and that's tested). I am able to run my reference programming books while I continue development on software and also, download and use apps. Now, hard drive space may be a problem, but it has not served as a problem for me yet. I sync my hard drive data with my sky drive account so, my laptop has everything that I create on this tablet and there is no real need to store large amounts of data on this device, I use it as a thin client. I, however, would not recommend this device if you are looking for a laptop replacement, but if you are in the market for a tablet that does more than the i-pad or any android tablet, I would recommend the HP envy x2, but if it not available, get the Lenovo lynx.
