Disagree (respectfully of course) with Bload

Bussard's polywell may or may not work. It stands ahead of ITER because in principle, net power units need not require billions of dollars to develop. The science can be adequately proven (or disproven) with much smaller amounts of funding.

I think that research like this stands to benefit humanity considerably. I would award such efforts a

A PASS

(with respects to BLoad's much harsher scoring system).

Like fusion?

Geothermal ... requires the right geology. In some places it will work. In many places it won't be economic to drill deep holes. In some places it won't be safe (will precipitate earth tremors).

Fusion ... well, ITER's costing an arm and a leg (USD9e9 ? something like that). Personally, I cannot see this as an economic solution without some serious engineering breakthroughs and enormous cost reductions.

Personally I'm hoping Robert Bussard's polywell works out. It might just save our bacon.

Steve, because he makes clever things that work.

Apple users

I'm an Apple Mac user since 1991, and I assert with some confidence that I am probably dumber than some El Reg readers. I use a Mac because it allows me to continue to be quite dumb about the mysterious inner workings of my computer while still doing quite useful stuff. So it is with great sadness I read these articles that Holy Steve (on whom be the Blessing of the OSX) has not provided the Mac Faithful with the protection that the Faithful require. I realise that at times the Form of the Browser does not lend itself to such Protection; that it is Sacrilegious to have a pure and minimalist interface overlaid with dialogs written in TechnoSpeak. However the Other Religion of the Mac Faithful (the Massage of the Hip Pocket Nerve) is at stake here. There are miscreants among us, whose sole aim in life is to spread confusion, despair, and dynamic linked libraries. Shall we allow them to Massage the Hip Pocket in reverse, and take from us what is rightfully due the Holy Steve (on whom be the Blessing of the OSX)? I say no! Bring on your Anti Phish Dialog! Bring on your Insecure Web Page Dialog! And whatever else will keep our money safe and warm until it is required by the Holy Steve (on whom be the Blessing etc etc).

Regards.

Cheaper to buy new than refurb ... Hmmm.

What about the lock?

Sorry Tony but your review didn't mention the deal-breaker for me ... the lack of a kensington lock slot on the MBA means it really is not suitable for my workspace.

I can handle the soldered-in battery. I can handle the ordinary graphics, the lack of ports ... but it's too easy to lift, and I cannot guarantee nobody will leave the door open and some miscreant dips in and lifts it. Too easy.
