I predict that Windows 8 will not catch on for mid-sized and large law firms. Windows 8 Enterprise is offered and has some interesting features, but the change is so huge that I see little potential for adoption by law firms.
Today our IT Manager showed me his iPad running a virtual instance of Windows 8 sourced from his home Mac. The interface has radical and interesting new flavour that sources apps and reminds me of my iPhone.
Windows 8 has only had peripheral mentions on Slaw to date.
