If you're doing digital/MCU work, I think a logic analyzer is far more valuable than a scope. With a scope: "Yep, it's sending something" With a LA: "Oh crap, the 57th byte was 0xFA when it should have been 0xFE" *find and fix firmware problem on MCU* |

Definitely yes: you can learn many things using it IMO. Forget DSO nanos and similar things, their bandwith is ridiculos. |

All you really need is a barrel to sleep in and some onions to keep the hunger away. ;) |

Problems can arise with different thresholds, especially with the probe leads, and with setup/hold time variations. Those problems are worse with modern logic families, and it is notable that nowadays LAs are relatively little used for professional electronic systems. |
