I really had to title it this was because my wife would think the same as I'm sure most of you can relate. A new device requires time. Time to get familiar with, touch and feel, looks, tweaks, and more. Thought I would share what I have become familiar with using my S4.
Del hit it on the head saying that I would consider my S2 a model T once I got my S4. The S2 was rock solid and very stable, a device I could rely on from day to day. After playing around with a few custom roms, tweaks, and such I believe the S4 has already filled that roll nicely.
As far as bench marks there is no comparison and just to show those interested I'll show you results from the S2 and the S4, starting with the S2.
As you can see by the benchmark results there really is no comparison for speed and performance.
I wasn't sure I would like the home button, but found out that I really like it better, course it's a matter of preference.
I was worried about getting the device unlocked, all the At&t bloatware and update notifications removed. Rooting was never a worry cause I knew there was an easy way. Unlocking was a breeze as well, not really concerned just didn't want to be stuck on EDGE with TMO.
I have everything tweaked in with my favorite apps such as Trickster, Advanced Task Manager, Rom ToolBox, Greenify, and of course my beloved Apex Launcher Pro. I don't like anything on the home screen except a weather widget. Everything else is accessed with buttons and gestures.
Once again I can't express enough thanks and gratitude towards PinStack, it's owner's, Staff, and Professionals. Because without all of you I wouldn't be writing this thread.
There you have it not much else to say other than I'm glad Del didn't have to send the squad to convince the wife to let me keep this great Samsung device.
