I currently have the Samsung i760 and enjoy the phone a good bit But, I am thinking about getting a new phone. The Omnia is going for about $15 new, which is a very enticing price and the fact that you can get a custom WM6.5 rom make its a bit more attractive(specially since I don't have that option on my i760).
Does WM6.5 make it faster and more efficient? I ask since this is a bit of an older phone. Additionally, how does the speed and device(w/6.1 or 6.5) compare to i760? How is the accuracy of the screen(the i760 wasn't that good)? Finally at this point is it really worth getting the Omnia or should I save and put my money towards a device like the HTC Eris at $100 or the Omnia II(when the prices lowers to $150)? Thank you.
