Not really. This is the fundamental principle of technology disruption. At some point one paradigm over-serves the market to such a degree that a new, less functional entrant comes in and starts to steal away market share. This happened most dramatically with hard disks, where 8" drives lost way to 5 1/4" even though they took a hit in storage capacity. Later 3 1/2" drives nibbled away at that even further, with the same penalties. Notebook-sized drives ate away at that, too, despite their limited capacity. Every time the driving factor was not performance or capacity, but convenience. Lugging a twenty pound hard drive around in your laptop wouldn't make any sense even if it could hold 400TB of data. Desktops yielded to notebooks, notebooks yielded to phones and tablets. General purpose migrates to the most convenient solution that's adequate for their needs.
