No offence, but lenovo's qc is not that good apparently. A few of my friends are using lenovo (thinkpad series). All of them are having problems with their laptop within a year.

I think there is an error in the title. Should be "worst", not "worse". By the way, back to the topic. I feel that the word "worst" is a little subjective. Worst in terms of what? Reliability? Price-specs-ratio? Merely price itself? I guess TS meant the word "worst" in terms of reliability. With regards to the debate between Windows and Mac OS X (or rather PCs vs Macs), here are my 2 cents. Seriously, people buy Macs for their OS and design, nothing else. In fact, if you haven't learnt how to use Windows or OS X, trust me, OS X is easier to learn. People who buy macs like the ease of usage, mainly for simplicity. In terms of reliability, they are not that reliable either ( iMac screen problems, macbook unibody cracks, macbook pros get pretty hot in tropical countries etc). Head on to macrumours forum or apple byte, and you'll see that there are quite a lot of people having defective units or problems after a period of usage. Service wise, I would say so so, not that great.

Some of you mentioned that Apple loves to keep quiet about Macs' problems, and secretly fix them. I have to agree with that. The recent Macbook white unibody is suffering the same fate as its predecessor, having the same crack problems as before. Although a lot of people are complaining about it, Apple still hasn't widely acknowledge the problem. Guess they are still figuring out what went wrong.

For Windows vs Mac OS X, I would say OS X is still at its growing stage. The OS still can't utilize flash applications properly. Whenever Mac users load websites with flash or playing some flash games, their Macs tend to heat up pretty fast (I think it shoots up the CPU usage a lot).

All the above are just my opinions and thoughts, and based on what I have read on the net.
