Ditto with a twist. The platforms we have traditionally used, the consumer PC market, (all inclusive: Windows, Mac & Linux), has been driven by the need for platforms that were adaptable to the needs of a few billion users worldwide. Users had no choice but to use one of these platforms to get email, web access and office-like apps - the primary use for most PCs. The musician/artist/scientist portion of that market was not so large but benefited from the growing demand forcing hardware prices down.
But now, with iPad and Android meeting most consumer needs in dirt cheap and quite elegant ways, the death of the cheap workstation platforms is highly likely. Most consumers do not need the connectivity or bandwidth that musicians, artists and scientists do and we will likely see our requirements ignored or at lest become more expensive to fulfill.
My advice to other 'tweakers' is to buy or build possibly your last cheap DAW workstation host now or soon, while the price-performance ratio is still affordable and while the hardware is even available. I suspect the consumer PC market will basically be discarded to Linux by iOS/Android though.
That said, there are amazing things coming out of the convergence of these platforms as Apple/MS/Google fight for the title of consumers' choice and as developers find niches for their special interests. I love my Android devices. We will certainly see more specialized audio hardware to support our niche market that takes full advantage of our recent handheld human interfaces (pads & pods, i & a) and pros will continue to buy high end custom solutions to stay on the cutting edge, some of which trickles down to us mortals. The rate of change is what is startling though. What used to take years to get to market now seems to take a few months at most. Most members of this forum would be tweakers by nature, IMO, who are enjoying the ride though. For those purists wanting the old ways, there are always the boutique gear providers, pawn shops, etc. Most musicians probably appreciate a good sound, regardless how it is sourced, and appreciate or have feet in both camps. Either way, it's a great time to be a geek musician.
