I have ran SMXI before but never with LMDE.
The only benefit I can see is if someone wants to go to Unstable and add Aptosid repos to safeguard against breakage. With the volatility that should happen with Unstable after Stable is released this doesn't sound like a good move right now (meaning moving to Unstable (Sid)).
Does SMXI have any other benefits? My video drivers work, I have dowloaded all I need from Synaptic.
Am I overlooking any other things that SMXI brings to the table?
Thanks for your opinion.
