Can I learn how to type using a laptop keyboard or do I need to effect a top keyboard?

The laptop keyboards have exactly the same layout as desktop keyboards, this is once it comes to parcels,
Numbers and num pad etc are not just the same, but provided you want tutorials that make you use letters, then a laptop is fine.
If you need to use num pad and numbers etc then basically buy a desktop keyboard and affix it to one of the usb ports on your laptop
