I'm definitely going to go to a back-up E66 for my daily phone and will prep the Omnia for an ebay sale, to get what I can from it. It's definitely a huge let down of a device, given its hardware.
The last straw was this weekend: a huge bunch of friends and I went on a weekend long trip to Atlantic City, NJ, to have fun and do a little gambling at Trump, Tropicana, Ceasars, et al. For the journey there and back, we rented a two tier, big silver party bus with amenities, food, drinks, second floor exotic girl poles, etc.
I brought my Omnia for its supposed picture capabilities only to be hugely let down. Nearly every single picture I took was a FAIL, all blurry, all awful, nearly all had to be deleted. My old 6650 flip managed impromptu quick shots better.
That, along with a large list of small things that bother me about it, make it not fun to have around.
It's definitely a phone for someone who likes to fiddle with settings, hacks, throwing custom ROMs on to it, etc. Phone hackers would probably love it.
Honestly, even as a tech nerd, I can't be bothered with that. Life's too short to spend all your time getting your expensive, high end phone to an acceptable, usable level. Besides, Symbian only really shines with button based hardware; with a touch level added on, it's like that animated gif head repeatedly slamming itself into a brick wall.
With what I recoup from it, I'll either go with a Nexus One or wait two months and pick up an iPhone 4.
