Got to disagree on the math here. You're only counting your power bill but not the laptop itself. That machine cost you maybe a grand, and running it hard for a month wears it out faster. For my small projects, the cloud is cheaper because I only pay for the few hours I actually use it, not 24/7. The calculators were spot on for my case, saving me from buying new hardware.

Oh my gosh, sixty bucks for blank discs? That's brutal! What a total scam, I'd be so mad.

cheat code for tight spots" is so right... i used to think anything under 0.5 was too scratchy but @lane.drew you got me trying a 0.3 and now i'm hooked for margin notes. total game changer.
