I returned my black 64GB one yesterday on the last day of the generous holiday return window -pun intended. I held on to it as long as I could to minimize my Surfaceless time. I'll be back to a MS store soon -the closest one is 2.5 hours away, to pick up a 128GB Pro. If I prefer it, I'll keep it; otherwise, I'll trade it in for another RT. Any comparisons to non-Windows devices are so meaningless to me, for multiple functionality reasons; plus, there is only one 1.5 lb/.68 kg tablet that has Office -the common currency in computing, SD expansion, a standard USB port, HDMI out, a kickstand and thin, very light keyboards/covers. I want these things; I need a Surface.
BTW, and with due respect to all, for my tastes and sensibilities, the (charcoal) Surface is the masculine tablet, or the most fit tablet for an adult male. Wink.
