I'm currently using MacBook Pro (Retina, 13-inch, Early 2013) and it's more then enough 🙂 I'm pretty happy with it. I just always wanted iMac, but 27" is toooo big for me, and now with 21.5 retina - well, I just want it 🙂
If I don't lie myself first 27" base model retina iMac started at $2499 when was relesed and next one was released with starting price at $1999. That kind of price drop I imagine for next 21.5" retina model February with Skylake 🙂 I'm not going for $500, but $200 will be very nice... this means that here will drop with 200 euro.
How is the current 21.5" model ? With SSD I assume it's more then enough for "heavy" tasks like ~50MB Photoshop files edit & some rare 720p videos edit for YouTube ? 🙂 My other usage is Sublime Text and browsing + YouTube. I'm not a gamer 🙂
