Could you enlighten us about how apple products aren't expensive?
Same for iMacs. Don't compare an iMac with a clone in a tower. Compare it to a similar form factor: all in one, quiet, low power consumption.
If you buy it over an Apple, you get what you deserve. The quality from Lenovo has been declining since they bought the brand from IBM. Thinkpad's are a SHADOW of their former glory, sadly.
Here's something people don't factor in when buying laptops: Your expensive MacBook Pro is having issues? Well, visit an Apple store and get it fixed!
Your expensive Lenovo is having issues? Well... mail it back...
But you still didn't make the comparison, you told other people to do it. Until you make the comparison, I'm still betting that the Lenovo cuts corners in a variety of ways to make the product cheaper, and as a consumer you have to accept those cost-cutting trade offs.
For example, while there are laptops much cheaper than the Air, the ultra books with similar specs, weight, battery life, and build quality aren't really cheaper. Another way to look at is that while Apple doesn't sell a $500 laptop, you don't get less in a $1,200 MBA than comparable $1,200 PC laptops.
