[myTouch 4G Q&A, Help & Troubleshooting] DaArtist401:
I've owned both so here r my positives and negatives....

Vibrant Positives:

-Screen

-Codec support and perfect 720p playback

-stock music player is better than on most androids

-Camera, is probably the best camera i've used on a phone, even better than iPhone 4's camera(my previous fav phone camera).

- TV Out

-16gb onboard storage, extended my overall storage to 32gb :)

- It's super lightweight. I say this is a plus because one time when i was jogging, i dropped the phone, but it was saved and didn't hit the floor as it was dangling off my headphones. Most heavier phones would've disconnected, fell and maybe shattered their screens,. *cough* iPhone,..

-3G on AT&T and T-Mobile if unlocked. This is very rare.

Vibrant Negatives:

- Device comes shipped with many issues.

- Design, although this is just my preference, I do not like it's iPhone 3GS inspired look. I still loved the fact that it's light tho, even if plasticy.

- Bluetooth,.. Can't connect wii controller for my games.

- ROMs and Development... Although developer support is increasing(i think), the majority of the first couple months in Vibrants development seemed to have been spent addressing all its shipped problems, lag, gps, among other things. Better ROMs are available now, but doesn't stack up to other android devices, specifically, HTC ones.

MyTouch 4G positives(current phone):

- Design,..Again, it's just a preference, but with this phone u have several color options. It has metal accents, sturdy feel. Plus i like having a touchpad, mostly for waking the device. Having LED lights is nice for messages. I am not very fond of its menu, search, back, and genius buttons tho. They r a little creaky.

- Bluetooth,..I can connect my wiimote an play any of my games with it :-D

- Stock Rom is stable and very functional

- ROMs and Development... U have very many options. My current favorite being MIUI roms because of their level of customization.

-FFC

Mytouch 4G negatives:

-Screen. U have to take a gamble with screens as u may know.

-Codec support out of box. Of course, u can get apps like Vplayer to play most files such as .avi . But it can't playback 720p like the Vibrant.

-No TV Out

-Camera,..I must stress this because believe me, i've been an HTC fan since 2006. My first smartphone was the Hermes(AT&T 8525), second being the HTC Tilt 1. Don't get me wrong, i love HTC, but i think they make the WORST cameras of ANY smartphone manufacturer. I know it sounds like quite the stretch, but i've owned a lot of smartphones. Even my old Blackberry Bold 9700 has a better camera. Even the last generation iPhone has better quality. The problem with the camera is they r extremely laggy if u have no SUNLIGHT. I literally mean u need sunlight, or an equivalent light source for the camera to be lag free. House lamps don't cut it, or anything else indoors for that matter. And the flash doesn't fix this problem. They just have bad, laggy cameras. Any slight movement blurs pics or vids badly. And trust me, i've tried many of HTC's current smartphones including the EVO, G2, and others. Same problem across every one of them.

Sorry for huge emphasis on camera and long post. I can't sleep currently and typing a lot helps lol(1:17am),.. In the end, for what i use my phone for, Mytouch 4G fits my daily use. I like the various roms, and wii control connectivity. I also like occasional FFC with my long distance friends/family who have EVOs and iPhone 4's. It also does everything else i need it to do without looking for fixes, GPS, everything. Developer support and rom availability is important thing for me because i like testing out different roms, doing Nandroid backups, etc.. MIUI was actually a selling point for me to choose the MyTouch 4G over any other phones(T-mobile phones specifically). Not to mention next gen snap dragon processor and 768mb ram. In the question about the Vibrant 4G,.. If it doesn't ship with all the issues of the previous Vibrant launch, it could potentially be better than the MyTouch 4G.
