At what point in time is the cost of tooling written off in your view?<p>I&#x27;ll grand you the $2600 price tag if you also tack on the 400K for the house to keep the setup dry and you assert that the creator only ever uses the laptop for this specific purpose.<p>You can&#x27;t factor in costs like that and then critique the DIY project because of it.  I&#x27;m sorry, that&#x27;s just not fair.
