[Galaxy S II General] zeotrope:
This should make all the sgs2 owners out there feel good since atrix was the main competition. Let me break down exactly what I liked about the Atrix (which *was* a great phone except for one major problem, more on that later)

Atrix

Pros:

- high resolution was great

- had a nice weighty feel in your hands

- tegra2 games were awesome (i'm looking at you galaxyOnFire2 HD)

- games in general ran amazingly well

- you can unlock the bootloader

Cons:

- took a while for the bootloader unlock to come through (was a great day when it did)

- comparing it to my friends nexus s i got the feeling that the colours on my screen were much less vibrant (colours on sgs2 are even better than nexus s)

- live wallpaper's made the whole UI choppy, no matter what rom or launcher I was running, strange because the tegra2 was so good with games, yet eveything lagged up from a simple LWP.

- HERE IS THE MAJOR ONE: after about 4 months of using the atrix, the touch functionality started to deteriorate. Nothing helped it, I flashed new roms, followed guides to wipe partitions, NOTHING worked. Basically, there was a 1/4 inch section about 3/4 inches away from the top of the screen that didnt respond to touch input.

AND later on a similar section on the bottom developed, this is ultimately why I decided to sell the phone on ebay (fully disclosing the issues with it of course)

the issue I'm talking about has been reported by a number of Atrix users, some were able to fix it with certain apps from the market and wiping partitions or caches, I was not one of those ones.

SGS2

Pros:

- bigger screen (depends on person, pro IMO)

- the colours are absolutely phenomenal. I have friends pick up my phone and go 'woah' once they see the colours

- fast as hell, right out of the box. the UI is like butter

- easy to flash new firmware versions, KI3 gave me an extra 20% battery life per day at minimum, and android 2.3.5 == awesome

- i quite like touchwiz 4. i didn't think I would, but it's nice to use and very smooth

-thin thin thin thin

Cons:

-i have 1 always green pixel, but to be honest i only ever would notice it using a dead pixel test app from the market and even then only when the screen is on red, can't see it on any other colour.

- resolution wasn't as good as the atrix! i know they used different methods to count total pixels, but at the end of the day, side by side, you could tell the atrix had more pixels and was 'sharper'

- almost would've liked a little more weight to the phone. though unlike certain reviews i definitely don't feel that it feels plasticy or cheap. it's just light.

- not the same support for games, GoF2 would be nice to play on this thing.

(i'm aware of chainfire3d, I tried to get it to work but GoF2 would load up *properly* except all the textures would be white, no idea why)

If it wasn't for the issue I had with the atrix I'd still have it (and 600 bucks in my pocket). The end result was I sold the atrix on ebay for around 300 (pretty good for not fully working, though the condition of the phone was mint).

However, I have to say that this is the greatest phone I have had the pleasure of using to date. I've been fiddling with it for a week, rooted it, flashed stuff with odin, played with CWM, upgraded firmwares/modems/radios and all that ****.

It's been awesome. Looking forward to spending some more time with this thing, checking out new UI's when I get bored of touchwiz, and all the awesome stuff that XDA has to offer. Keep up the great work guys.

**Note: I was unable to return my atrix because it was not under warranty, I live in canada and bought it on ebay (from the states) before it was released in canada, I called motorola and complained but they weren't having it.
