[Samsung Galaxy Mega] x2h:
Upgraded from Note 2 to Mega and here's some thoughts after using it for nearly a week. This is based on the unrooted stock rom.

Likes:

1. Bigger, brighter, and whiter screen on the Mega. It makes watching video on the phone a real pleasure. The white colors on my Note 2 are always yellowish and blacks are clipped.

2. More natural color compared to the Note 2. My favorite screen mode is "standard".

3. Handles videos well. Played 720p mkv action movies with DTS audio and it handles them without a single hiccup. I used Archos Player to do that. Didn't test the stock video player since it doesn't support DTS audio

4. Easier to grab compared to Note 2.

5. The power button and the volume rocker are easier to press.

6. Higher DPI. It seems Samsung is using higher DPI for fonts, which makes the phone feel more like a tablet than a phone.

Dislikes:

1. No S pen. If you use that a lot, then you are going to miss it. I use it sometimes but I can manage the life without it.

2. No AC3 support. Sammy wants to save money here therefore you will have to buy a third party player with AC3 and/or DTS decoding. Of course if you don't mind, you could always re encode mkv movies to MP4 with AAC or mp3 audio which is then supported. I am just lazy. :o

3. Not enough accessories on the market. This is not he most popular phone so not so many accessories are available yet. Hope there will be more.

4. The rear camera lens: why does it have to stick out so much from the back??? Look at the iPhone, and some Sony phones. They don't have that ugly protrusion at the back!

5. Although easier to grab compared to Note 2, it is still a slippery phone. I am getting a rubberized back case to improve that.

6. When I am typing, the predicted words comes up later than on the Note 2. It's noticeable but not annoying yet because I don't type that fast. You may not like it if you are a turbo texter.

Everything else is pretty much the same as my Note 2. The Mega may not have the fastest CPU in the world, and it doesn't have 3 Gb of ram, but I didn't experience much lag at all.

Games:

I don't play games so I asked my 8 year old boy to test it for me. His answer is "no lags". Of course he didn't test all those CPU and GPU intensive games so don't quote me on that.

Battery life:

At full blast which means full brightness, all radios on, it lasts between 5 to 6 hours. I am quite impressed.

Screen sharpness:

being a 720p phone with the largest screen (am I right? ), I was worried that I will see a lot of pixelation. In reality I hardly notice that at all. I am sure a 1080p screen will look nicer. Maybe we will see that in Mega 2? Let's hope for one. And I don't mind if they make the screen even larger. If they can narrow the bezel like they did with the Note 3, they can make a 6.5 inch screen without making the phone larger. :D

Pocketability: it fits in my pant pockets but I have to admit it reaching the limit.

Final thoughts: Obviously there's a limit how big a phone can be. With the Note 3 being nearly physically identical to the Note 2, it looks like Samsung has decided that's the largest size they are willing to go if they wanted to keep the Note series popular. Hence the Mega looks like their experimental device: let's throw everything on the wall and see what sticks. It will be interesting to see how the market responds to the Mega within the next few months.

Conclusion: I am keeping the Mega and selling my Note 2. :D
