From the article, "It’s about getting used to the PS4 GUI. I’m more comfortable with the old school PS3, and even PSP, interfaces. [Jenni Lada] liked the XMB, and I enjoyed customizing my PS3 backgrounds. I wasn’t sure I’d dig the PS4 GUI.
I wish I could say I immediately experienced a complete 180 once I turned on my PS4 for the first time, but there was an adjustment period. I’m getting used the PS4 GUI, and even though there is a bit of information overload, I can honestly say I’m liking how fast and responsive it is.
