indest did a fairly good job on that analysis of the laptop. For me, i LOVE my Yoga 2 Pro but i wouldn't recommend it to anyone really. its has its share of heartaches which really sucks. There are a couple of things that indest noted that i do disagree with though.
- track pad deselecting. This is an issue with a lot of trackpads and more specifically glass trackpads like this one. Glass trackpads have almost the same sensitivity as a smartphones display, so its really easy to deselect something. Its just the nature of the device.
- The wifi issue is a hit or a miss from what i read. The one i have is fine and im using a 4-5 year old router at this point. The one thing that i dont understand right now is that this Laptop wifi card is ac spec meaning dual band, but i can not connect to my 5Ghz band but others using linux can access it. Not sure if its a driver issue or something.
- trackpad being a grease magnet is just the nature of the trackpad. Its glass, just like a modern macbook, but unlike a modern macbook the yoga has a black background meaning smudges are easy to see. The reason why you can't see it on a macbook is because the background behind the glass is a neutral color, but if you wipe it down i guarantee that it'll have just as much grease/oil
- I never have an overheating issue on mine. But i wouldn't be surprised if others did. The laptop can be awaken by a couple of things and if it does become awake then yes it would overheat just like any laptop.
- The micro hdmi is too recessed though you can get it working just by wiggling the connector around a bit. Just be careful not to move it once you get the picture going through.
- Keyboard backlight, IMO, is perfect. Its only dimmer than most laptops in their brightest setting. The brightest setting i find to be annoying in most laptops. I usually opt out to 75% maximum. The difference between the Yoga and the other is that its either on or off. But for me i can't argue because the brightness is on the backlighting is perfect.
The main drawback from this laptop is bloatware and a lot of proprietary software to just run the **bleep** thing. But, to be fair to lenovo but it is still unexcusable, other OEM's are also doing the same thing with their laptops, but at least Lenovo's version has some usefulness to them. Also considering that you are looking for an ultrabook i imagine you understand that as a drawback from moving to ultrabook you dont expect to be hooking up 5 devices onto this guy.
Honestly, get the Thinkpad X1 Carbon Version 2. The one they just released. I would say get the Yoga 2 Pro if they still had the sale i got mine (i5, 8GB RAM, and 256GB SSD for $1050 you can't beat that period). The X1 Carbon is just cooler in general. Its specs aren't insane beastly in comparison, but it is a much subtle laptop.The only drawback i can think of is the red iconic nipple you get with thinkpads and price/performance ratio. Other than that its not a bad alternative at all. PLUS you get to say "My laptop is made from carbon fiber." That alone is what made me almost buy the X1.
