Is "last but not least" only used in speech?

Not at all! Although it's more commonly used in speeches to give thanks to someone, or to introduce a list of items, you can use it in writing as well! Ex: Last but not least, I'd like to thank my parents for their love and support. (Speech) Ex: Last but not least, the weight of the item is crucial to calculating velocity. (Writing)
