You don't have to type capitals, and you have aliases just as terse and understandable (?) as standard unix commands: gci, iwr, ri, etc. So you don't have to type them if you don't want to. The But if you forget, it's nice to have them. And for commands at the margin of your memory they're entirely discoverable (including the aliases). It's not necessarily obvious when you start, but it's actually super useful to be able to use and re-use all your skills for selecting and filtering data. Being able to 'get-alias | where definition -like *item' is a great way to discover the terse aliases for file operations, for example.
