[Captivate General] Tinyboss:
I owned a Captivate for two years, and a month ago I used my upgrade to get a gray HTC One X. I'm posting this review in here because it's specifically focused on my experience upgrading from the Captivate. I hope that's okay...

Let's get the obvious stuff out of the way. It's two years newer, so it has more RAM, more cores, more GHz. It's way faster and smoother. Okay, moving on.

GOOD

Screen - The screen, oh my God, the screen. The first thing I noticed about the Cappy in the store was the PenTile display (though I didn't know what that was at the time). I thought, "what's with the jagged edges on the text?" About a day into using the Captivate, I stopped noticing it, and it never bothered me. But when I saw the HOX's screen, I instantly knew what I'd been missing. Now, I know the resolution is much higher, so this is not meant to be a SLCD2/SAMOLED comparison. Just know that the screen is breathtakingly sharp and smooth. I do miss the Captivate's deep, inky, perfect blacks, but it's a tiny price to pay. The screen is also physically larger, which I love, but if you have small hands it could be an issue.

Camera(s) - There's not much to say about the front-facing camera except for one important fact: it exists. I think the Cappy was the last high-end phone not to include one, and it was really starting to chafe. Likewise, the flash on the main camera is a nice addition. The main camera itself is very good, although maybe it doesn't quite live up to the hype ("best phone camera ever") that it was getting around launch time.

The camera app interface is a pleasure to use, and I've had a blast playing around with slow-motion video. Another great feature of the camera is that it's very fast to launch--by default you can access it from the unlock screen, and it takes maybe one second to load up. Instead of switching between snapshot mode and video mode, there are separate buttons for each, and they're always available. Seriously, it's just easy, and I'd be reluctant to flash a ROM that didn't have access to the stock camera app, it's that good.

GPS - It works! It works well! With support for GLONASS, I've seen GPS Status reporting a lock on 15/23 satellites (3m accuracy). Once a steady lock is achieved, GLONASS is disabled and it changes to something like 8/9, but if I move the phone so that it can't get a good signal (like the floorboard of my car), it automatically re-enables GLONASS for the extra accuracy.

NEUTRAL

Unibody construction - This could very easily be a huge NEGATIVE, depending on your own needs/preferences. I went two years with the stock Captivate battery and with a 2GB SD card that never had anything on it. So for me, the non-replaceable battery and lack of an SD card slot are only minor downsides, made up for by the stylish look and very solid feel of the machined body. Although I never felt like there was any problem with the Captivate's build quality, the One X just feels like a solid brick in the hand, hard to describe the difference, but it's significant.

BAD

Power button - Admittedly this is a minor thing, but I HATE the placement of the power button on the top of the phone. Almost one month later and I still haven't found a comfortable one-handed way to push it without mashing the volume rocker. The power button is probably the thing I miss most about my Cappy!

Screen glass - It supposedly has Gorilla Glass 2, but whatever it is, I suspect it's not as scratch resistant as the Captivate's glass. Or it could just be that the phone's physical design puts the glass more "out there". Mine already has a scratch that's worse than anything the Captivate picked up in two years without a screen protector. It can be felt with a fingernail (although it's unnoticeable in normal use). I dislike screen protectors, but I may have to use one anyway.

These next three are BAD as well, but they could potentially be fixed with software updates, either official or otherwise. However, the GPS fiasco with the Captivate taught me never to assume that some problem is just a glitch that will get taken care of shortly! So here they are:

Multitasking - Read about it here. It sucks and, so far at least, HTC seems to be saying it's working as designed. There are various fixes being promoted, with some swearing they work and others saying they do nothing--so familiar! However, I do believe that once something like CM9 is available, it'll be fixed (but read below about dev support). This isn't hardware.

Data issues - There are problems maintaining connections to wifi and mobile data. Hopefully this is another consequence of HTC being overzealous with memory/battery management and will be fixed in software, but I suppose there's a small chance that it's hardware.

Dev support - It's locked down, hard. There are talented devs working on it, and there is good progress. I don't doubt that we'll have everything eventually, but the devs are really having to fight against HTC (because AT&T is leaning on them) to do it. Also, it's brickable--I haven't dared to do anything to it yet for fear of bricking it, and I really miss the Captivate's resilience in that area.
