[ubuntu] Are this Laptops Compatible with Ubuntu?

I'm plaing to purchase a new laptop tomorow (mostly for studies and general use) and I'm wondering if any of this are compatible with Ubuntu.

1) There is this Asus model which is published at this store as one of number of models but they specify the hardware included in it (It's mostly Hebrew website but you can see the important parts in English):

2) There is this Lenovo Model which looks alright but I read online that the screen is bit weak and tend to break, still will it support Ubuntu? :

* Intel i3:

3) Next one is a model from company called Fujitsu which I'm not familiar with so if any of you had one of their laptops I'll appreciate your input:

Whichever model I'll pick I plan to move the HDD into the DVD-RW spot (replace it) and install an SSD (probably 120GB should suffice) instead for the OS.

First time I'm purchasing a laptop specifically for Linux and I could really use some help to pick the correct one.

Any of those are compatible with Ubuntu? if does which one will you recommend?

Thanks
