Cords are a hassle, but they deliver harnessable power to reasonably compact tools - that's the only reason I put up with them.
And they aren't universally beneficial either - I own a corded chainsaw ( very reputable brand, mind you - it's a Stihl, they don't come any better ), and it s*cks big time. The balance is off, it's a lot less easy to handle and even less powerful then my nice tophandle pruning saw....
I wouldn't dream of taking it up into a tree canopy, the cord would weigh it down severely and besides: there are more than enough hazards to keep me occupied without adding the risk of electrocution to it, thank you! And even my Silky handsaw almost outperforms it anyway...
I've used quite a few cordless tools, and they sure have their place. I've used the first Bosch cordless hammerdrill inside of a computer room, where they wouldn't risk contaminating the grid for fear of the massive UPS kicking in and starting the 1600 HP Dieselgenerator. In fact that was a very good tool, and that must have been almost 20 years ago.....
I've used a ( cordless! ) welding generator inside a fully RF shielded Faraday's cage to reposition mounting points for a hypercubed workstation farm that served some spooky intelligence use - couldn't have done that with a corded welder as well......
I worked on a farm as well, and although 3 phase power was available in a couple of spots and single phase outlets were abundant - the ability to use a powertool out in the meadow fixing a fence is a BIG plus.... lagbolts and cordless impacts are e great combo for anyone creating fences. ( A big John Deere with a frontloader to pull out the old posts and push in the new ones helps a lot too - but hey, even that is a cordless tool.... )
Bottom line: cordless tools have their use, and their usability is spreading like an inkspot. Don't fight it, enjoy it !
It all boils down to harnessing power - the grid is just one way of distributing it. Fuel is another one, and I think perhaps fuel cells may find their way into powertools as well.
I definitely see your point Brice, but I don't think the development effort "spared" from NOT developing cordless technology would have benefited quality: the industry already knows how to develop quality tools, and doesn't really seem very interested, save a few exceptions.
Most manufacturers seem more interested in making their tools cheaper, lighter and using materials and construction methods that only just barely meet the defined specifications - a lot of money and effort is put into finite element analysis modeling to prevent tools to have any quality headroom.... because that costs in mass-production.
In the NEAR future, I don't see much use for cordless tools that produce dust in any amount. If you need dustcollection anyway, why bother loosing the cord? So cordless powersanders may not be your best investment plan for the moment.
But how about sawing? The thinner the kerf, the less dust AND the less power needed... so a cordless rail-compatible plungesaw sporting a superstiff blade with a nice clean 1/64" kerf and a neat high-tech nano-particle non-drag coating may well be your next most wanted Festool.....
