I'd get one...but it seems you have to be able to paint to use it.
And to your question...when I tell folks that the preparation and clean up take 3-4 times longer than it takes to drink a double shot, my already questionable sanity is no longer a matter of question for them...
See the popularity of Nespresso or Keurig...pop in a cartridge, push a button, walk away and when you come back...coffee. The idea of grinding, loading the PF, tamping, and standing there while your double shot id extracted is a pain...but one some are willing to go through.
Please understand Keurig, automatic machine, Nespresso users...I'm not knocking it. If it makes coffee that you enjoy...that's all that counts. And the convenience and lack of mess endemic to grinding, etc. certainly has it's charm.
Finally, in fairness to the roast it - grind it - brew it machine...it looks as if it is meant for drip coffee production...so fine control of the grind is less crucial (not unnecessary, but less crucial than with espresso.) I still say using bean with zero post roast resting time will give you mighty tingly coffee!
