Galaxy Note 3 is being shipped out and the question for already Note 2 owners is that: Is it worth updating from Note 2 to Note 3? Since you may get your Note 3 either with contract, unlocked or some other ways, we don't discuss about the price and we just compare both devices in different aspects and let you decide, if it is worth updating to Note 3 or not.
Note that you may have read many comparisons with full of numbers and benchmarks, but this comparison focuses on the difference of these devices based on usual usage by regular people (and not some geeks)

2. Note 3 vs Note 2: Design
The Achilles heel of Galaxy devices is their plastic body and we can see this poly carbonate (read it plastic) on the latest version of Note series as well. But Samsung used some leather finish, with stitching around the borders to make the device look more elegant and stylish. If you already own a Galaxy Note 2, you will feel the difference while holding Note 3. But since it is completely up to your taste, we can have no suggestion.

3. Note 3 vs Note 2: Display
Super AMOLED has been used for both devices and the difference is about screen size and pixels which has been increased to 5.7 inches and 1080 x 1920 pixels respectively. Although Note 3's display is sharper, but we don't find this improvement a strong reason to upgrade from Note 2 to Note 3.

4. Note 3 vs Note 2: Hardware
Go back and look at the comparison table again to see which hardware features have been improved. If you are a geek, then this improvement is kind of exciting for you, especially after reviewing available benchmarks. But is it also a significant improvement for regular users who just do some usual tasks with their device? We would say NO!

5. Note 3 vs Note 2: Software - Android OS
Galaxy Note 3 is one of the very first not Nexus devices, which is shipped with Jelly Bean 4.3 and we really expect to see Android KiKat 4.4 running on the device too. On the other side, Galaxy Note 2 is getting an update to upgrade from 4.1.2 to 4.3 on October and November. Since we have no insight about the KitKat, we can just say there is no reason to be upset about not getting JB 4.3 on your device if you are running a Jelly Bean (4.1 or 4.2). Read more about Jelly Bean 4.3 Features.

6. Note 3 vs Note 2: Software - TouchWiz
Well, this part is where Note 3 scores far more and better than Note 2. The improved Multi Window with the ability to open 2 pages of the same application at the same time, Air Command, Action Memo, S Finder, and Pen Window to open a floating window to run an application in it, are really practical and too useful to ignore. We are not sure if Note 2 is going to get any of these new features.

7. Note 3 vs Note 2: Camera
"Higher Megapixels doesn't necessarily mean higher quality". Considering this famous quote, you shouldn't expect over 50% improvement in photo quality, since the megapixel has increased from 8MP to 13Mp. Galaxy Note 3 offers some of great Galaxy S4 camera features like Dual Shot.
Speaking of video features, the ability to capture 4K videos seems to be more for marketing purposes, rather than some tangible and practical feature which gets used often.

8. Note 3 vs Note 2: Verdict
First of all, we should say we really loved the new look of Galaxy Note 3 with those changes in the back, S Pen design, and the fact that Note 3 is lighter, faster, bigger and thinner than Note 2. Other than improvement in the design which depends entirely on your taste, we can name new software features as the only feature that has been really improved during the last year.

So, is it worth updating from Note 2 to Note 3?
