Both my wife and I bought tablets over the past weekend. I purchased a Note 10 and the better half bought an iPad4.
Right away I saw the far superior screen of the iPad4: the obvious is that more fits on the screen (web pages, photos, etc.). The detail of text looks so crisp and easy on the eyes with no jagged edges. The colors on the iPad are more accurate and pleasing even against the Standard, Vivid (yuck) and Cinema options of the Note.
For browsing I tested the stock browser and Chrome against Safari. Clearing the cache and rebooting both units I tested pages and Safari beat the Note 10 every time for loading the sites. Not by a huge margin but at least 2-5 sec gap.
Without jail breaking the iPad doesn't have widgets, custom launchers or re-sizable windows. Also missing is a stylus (you can always buy one though) and a SD card slot. Too me this is not a big deal, you end up opening the widget to view the entire app anyway; the widget is a preview most of the time. As for the extra space, I stream all my data from a 3TB network drive and only keep the files I really need on the device itself; space is not an issue. The simplicity of iOS is actually appealing to me; its fast, stable and secure.
I took my Note 10 back and there are now 2 iPad4 devices in the house.
