5 out of 5 eggsGreat Ultrabook!!!

Pros: Slim and sleek design
Core I5
32gb ssd
500gb hdd
light weight
quite fan

Easily installed fresh windows 8 on ssd by disabling rapid start in bios and getting the disk drive drivers from a google search. Painless driver installation. All in all a very good ultrabook especially for $599... received one manufactured on 06/12/2012 haven't had any problems with wifi.

Cons: none

Other Thoughts: If you haven't already buy one its quality that you'd expect from Lenovo

4 out of 5 eggsGood laptop but OEM install is rubish...

Pros: I have owned this laptop for roughly 6 months, and have a love/hate relationship. I put Ubuntu Linux on it and love it, but it was a nightmare to get it that point. See Cons...
-Very lightweight
-Very fast
-Rather stylish, emulates macbook without the price tag.
-Actually has a NIC
-Long battery life
-Don't have hold down the base to open the screen, resistance is just right.

Cons: OK...if you are serious about this laptop, then here's what you need to know:

-Beware IRST, especially if you intend to reinstall the OS. This comes with no recovery media, only a recovery partitiion which must be lost in order to reload an OS from scratch without bloatware. Also invalidates factory warranty. DISABLE IRST ASAP in the BIOS.

-Forget about the Windows 7 OEM install this comes with, it is preloaded in most messed up way i have ever seen. It uses a recently developed Intel technology called Intel Rapid Start Technology (IRST for short). It automatically puts the computer in hibernation after a short amount of time in sleep mode. The system BIOS is programmed to BYPASS the "F2 to enter setup" prompt when in hibernation mode. This is bad if you blow away the OEM partition while the BIOS thinks it is in hibernation mode. You cannot get back into the BIOS until you flash it from a windows environment. BIG PAIN, i've been there.

-2nd weird thing is that the SSD and Conventional hard drive in a RAID configuration...what the heck!!...They use the SSD to cache the hibernate file for a quick resume from hibernation. Shaves off about 5 seconds, but not worth the headache. To reinstall the OS, you must disable IRST in the BIOS and change the disk controller from RAID to AHCI mode. Then, your partitions are unreadable and you need to completely rewrite the partition table. This can be done from the Windows or Ubuntu startup installation routines. You need a 4GB flash drive to setup for Linux or Windows install. To use the existing Win7 OEM license, you also need an OEM windows 7 home Disc image which is difficult to find for a home user. I work in a IT shop, so it was easy. Once your SSD and Conventional hard drive show up as seperate disks, then you can install your OS directly to the SSD for quick boots.
-Small con, the trackpad is unusually large, and is easy to graze with your palms while typing, I use travel mouse, and disable the trackpad because of my ridiculously large and clumsy hands.

Other Thoughts: After getting this laptop extactly the way I wanted it, I have really enjoyed using it with Ubuntu Linux. All hardware works great in Ubuntu. I installed Oracle VirtualBox (free) and I able to install my copy of Windows 8 Pro as a VM and have plenty of storage for it on the 500GB HD.

1 out of 5 eggs$700 Brick

Pros: It is a nice looking paperweight

Cons: Has ton's of pre-loaded software that I didn't want. Can't upgrade to windows 8 because it can't find the hard drives. Rebooted the computer and a windows error. Called customer support, they said that since it is a software issue, I would have to pay a bunch of money to get a CD. The laptop does not have a drive so I would need to get a USB disk drive. This is the worst purchase I have made in my entire life.
