Pros:
• Pressure sensitive stylus a huge plus for note takers and artists
• Same great camera as Galaxy SII
• Screen size is great for movie and web browsing
• High resolution Super AMOLED display
• Snappy Performance
• LTE is amazing (where available)
• Long lasting battery

Cons:
• Too large to be practical for most users
• Screen uses PenTile pixel matrix
• Doesn't have Ice Cream Sandwich
• Touchwiz brings little to the table
• AT&T's LTE coverage is nearly non-existent
• Handwriting recognition is half-baked
• International edition has better SOC

Note:
I'm located in a fringe area of AT&T coverage map (for both data and voice), and as such cannot give an accurate rating of call quality or reception at this time.
