I have both, i see the benefits of a notebook. But it has it's limitations.
- Screen is not as good(i have a samsung 173p which has extremely good viewing angles and image quality)
- Heat, if anything in a laptop gets hot the entire thing/a lot of it gets hot.
- Maintainability, laptops are less easy to service
- Durability, notebooks need much more care to ensure they work well.
- Storage space(my notebook has a 80 gb harddrive, that would not be enough...
