"If time is money, this is VERY expensive machine"1.5 starson by dfrieds
Pros: Great keyboard
Great size, weight
Cons: AWEFUL networking software, causes several minute delays and crash to MSFT Explorer
Brightness of screen sometimes gets set at certain level and can not be changed w/out reboot
Crashes and freezes too often
Summary: Bought the laptop b/c I love Thinkpad machines and have used more expensive products in the past. Size, weight and keyboard were also very appealing. I primarily use for Internet, MSFT office applications and e-mail so figured less powered machine would be fine. In general, serves those functions acceptably... when not choking on networking SW.
Lenovo's networking SW is about as bad as it can get, and frequently causes system to hang indefinitely as it searches for Wi-FI networks. I end up having to re-start Windows Explorer then wait again for it to find a network. This can take several minutes - sometimes up to 10 minutes(!). It happens almost every time I leave my default network. This single issue is enough for me to realize that buying the machine was a mistake. I assume the problem is a combination that the system is underpowered, and Lenovo put out horrible SW that was not adequately tested. Either way, I am going to chalk this up as a ~$600 mistake that didn't save me money after all.
I also realized that I also spend at least a little time viewing photos and other activities that run much faster with more fully-powered machines. Again, I think the lesson is that the lower powered machines are not actually a great value. They are cheap, but frustration caused by WAITING for things to happen is not worth it.
One other lesson learned: seems to make sense to buy a system only after it has spent several months in the market. User reviews like these would have prevented me from making the purchase. Somehow the "professional" reviews are all relatively rosy. I guess they don't have the benefit of constant use... and in this case, frustration.
