venting
I work in landscaping and I can do any job that people do with these types of power tools faster and easier without power tools because THEY ARE SO FUCKING HEAVY
Holding up a brush or hedge cutter over your head is actually much more effort than swinging a machete. I will die on this hill. Dudes just wanna play with power tools.

Chainsaws? Are you kidding me? I can cut down a tree with an axe or an actual saw while you're still tensioning the chain, making sure you have enough oil and so on. Plus the hand tools are statistically much safer. Chainsaws aren't for cutting down one tree, they're for quickly clearcutting an entire forest while the boss hires fewer lumberjacks.

Now some chainsaws are better than others, and this was really mostly a maintenance issue, right? But my feeling is that a LOT of the time saved with power tools gets eaten up by fiddling around with them, changing oil, changing filters, getting gas, getting spare parts, etc. The electric ones are slightly better in this regard, but not perfect.
Hand tools obviously require maintenance too but it's generally much simpler and takes less time (wash off, sharpen, oil before storage)
re: venting
Other half was out using an electric chainsaw to trim large branches in the yard. Asked me to come out and help, as it was taking a ridiculous amount of time and effort to get through them.
After I got back from the store with a new chain blade for the chainsaw it took a few seconds per branch.
