What's the point of using Linux? I never understand why people would go that way as there's no software for Linux. What can you do with it other than common web surfing and email?
Sorry but that is just wrong. It's just like the many windows users who says there's no software for macs.
I don't mean to start a flamewar here... Just pointing out some things:
As others said, there are alot of good programs for linux and if you must use the ones that doesn't exist, you can virtualize them (just like many mac users do with parallels or wathever).
Also you can make linux to what you like and make it fit your needs. If you are a normal user, you can use it as a normal OS.
If you have knowledge about how the system works, you can change anything you want.
You don't need to rely on a company to keep you safe, you can do it your self (and with others).
I am a mac user now (1,5 years), before that I was a linux user (1 year) and before that windows (many years).
It's great to have the possibility to choose between OS:es.
Everyone has his/her own needs.
If I had to choose a PC laptop I'd wait for the Lenovo X300 or maybe go Dell XPS [insert numbers here].
I would really miss OSX though... It's my favourite OS at the moment
(but at the same time I also think open source is the future)

I'd also miss the nice design and feel of the apple computers...
well.
To summarize:
Lenovo X300 (also fits in manila folder) or Dell XPS [insert number here].
edit:
but I don't know about the lenovo... it'll be cool but very expensive....
