Re: you got it wrong...
You know that funny word, "portable"? Do you understand "lightweight"? People looking for the kind of thing that is hardly bigger than an A4 block of paper are not interested in carrying around separate disc drives or swapping in and out SD cards and, news for you, a £30 USB drive is cheap for a reason - not because it is extra durable or reliable, especially when being carried around.
Even at home or in an office, most of us get pissed off with finding shelf or desk space for a myriad extra drives, cables, power supplies ....
Those days are gone, hence for most of the world, laptops ar replacing desktops with all the space they require unless you really need a vast amount of power for some specialised or badly written application. Wireless is replacing ethernet cables, ultrabooks are even replacing laptops. Come out of your cave and look around at how the rest of the world has evolved.
Lots of people have realised that throwing money at the problem can work out cheaper than making do and certainly make life pleasanter and, throwing enough at the right time can even be cheaper in the medium to long run.
