There are some standards like Mini PCI cards that alot of laptops use but I predict there will be a standard when hell gets a lot cooler. IT is a simple matter of brand differentiation. Look at the Sony Vaio, it looks like a Sony even from 100 feet away but look at alot of laptops and they all look the same because they come from the same manufacturer. (You mean Dell doesn't make their own laptops?). Personally I am really likeing the Asus laptops myself. I am not looking for the most colorful or the thinnest laptop.
