Ok, so I bought an Omnia over the weekend and I'm loving it! Was comparing it between the Touch Diamond, but I have to say even though the TFlo3D interface is very nice eye candy, it's so damm slowww. It was a live demo set with data on it so I have to say it provides a fair representation of real-life scenarios. It literally took 2-3 secs to change to the next menu.
The interface on the Omnia was almost instant, there is still a slight lag, but when I was comparing it with my cousin's iPhone, it was only marginally slower. Touch interface is very responsive, colours when viewing images especially in full screen mode is vibrant and usual 350MB videos has no jerkiness during playback and looks extremely good in widescreen format. Images during 3G video calls are clear with hardly any background noise and the sound of both parties are loud and clear. GPS works very well; takes under 30secs to pick up your location and of course it's 5MP camera with flash takes decent photos and videos. With full resolution during photo-taking, the inbuilt 16GB memory can hold around 20,000 images and it also came with an additional 1GB microSD card.
Overall I'm very impressed with the Omnia and have no complains so far, a minor problem is that the motion sensor for the auto rotation might be a tad sensitive, though I have not adjusted it yet. But the best part of all is I only paid about USD$260 for it with a 24-mth extension on my current mobile subscription and a trade-in for my O2 Atom. The usual price if I'm not wrong without any contract is about USD$800+ :lol:
