As part of the celebrations for its twentieth anniversary, our sister magazine MacFormat is running a poll to find the best Apple product of the last 20 years.

It's still open – you can and should vote here, not least because you could win an iPad mini – but we've had a peek at how the votes are stacking up so far, and they've got us thinking; did Apple make better products when it was actually a less successful company?

The current top five in the poll reads like this: iPhone 5, MacBook Air, iPad 4, iPhone 4S, iPad mini. Now, nobody in their right mind – [witty aside about Android fanboys] – is going to argue that those aren't stunning things. Nobody's going to seriously contend that these slick, supremely beautifully crafted artefacts aren't part of the reason Apple is currently one of the most successful companies the world has ever seen.

Sign of the times

But it's a bit of a boring list; it's basically a description of Apple's current line-up. MacFormat, after all, is running a poll to find the best Apple product of the last 20 years, not the best product you can walk into an Apple Store and buy today; you have to get to 13 in the rankings to see a product introduced before the turn of the century, and overall it's a list hugely dominated by very recent products.

Yet there are so many things that Apple has produced throughout the last two decades that were hugely innovative, that disrupted stagnant businesses or that flat-out triggered an animalistic 'want' when you first saw it.

The G4 Cube, for example. Sure, it was a commercial failure, but it's glorious, and the way you drew the core out from the case never felt anything less than sci-fi.

The PowerBook Duo. A slim, light laptop that you slotted into a full desktop case to give it more power and more storage when you weren't on the go. Hell, we'd buy that today; quite apart from the practicalities of balancing power and portability, the act of slipping a laptop – clunk! – into a desktop case just still feels cool.

Newton? The spiritual predecessor to the iPad, and hugely ahead of its time; handling one now still gives you that tingle, and you could argue Apple's never made a computer cuter than the eMate.

Or what about iMacs past? The slim aluminium model is beautiful, but in a cold, soulless way. Nothing has equalled the charm (or, to be frank, the ergonomic triumph) of the 'Anglepoise' iMac G4, and the original iMac G3 should be lauded and remembered not just for its friendly, colourful transparent plastics, but also because it unequivocally marked the point at which Apple started to get its mojo back, propelling it to its current success.

What about Apple's software?

And that's before you get to software and services. You could argue – although perhaps only after a few pints – that Xcode is hugely important since it lets developers create the apps that kick-started the app revolution. You could also argue – though perhaps only after switching to whisky – that iMovie marked a moment when we stopped using our computers for word processing and spreadsheets and started using them for fun.

For – and this is the kind of phrase you can only utter with a straight face once you are drunk – lifestyle stuff.

We did a big, serious bit of research at the start of the year, and one of the things it shows is that the general public still sees Apple as being a hugely innovative company, but there's a growing feeling among the alpha geeks in the industry that it's faltering.
