Besides price, brands, designs and self requirements, The followings must be taken into consideraton:
(1)Some parts for a modern laptop have no corresponding part in a desktop computer. Intel, Asus, Compal, Quanta and other laptop manufacturers had created Common Building Block standard for laptop parts.
(2)Standardization issues: there are still no firm worldwide standards relating to today's laptops' form factors internally, such as supply of electric voltage, motherboard layouts, internal adapters used in connecting the hard disk, optical drive, LCD cable, keyboard and floppy drive to the main board. Most affected by this are uneducated users, especially if they attempt to connect their laptops with incompatible hardware or power adapters.
(3) Compatibility issues: A significant point to note is that the vast majority of laptops on the market are manufactured by a small handful of ODMs.Some mostly internal or proprietary parts made by laptop producers aren't interchangeable with other manufacturers' products, so that the same manufacturer's components are used with the laptop they produced.
(4)Upgradeability: Laptops' upgradeability is severely limited, both for technical and economic reasons.
