I have tested the Fascinate enough to agree it is a sweet device, but the Inc kicks its butt with 2.2. Whenever this puppy gets 2.2, IMO the Inc will be second place.
I am happy to wait a few months and see how things pan out for several issues:
1. When will there actually be a rooted rom? A lot of talk about the device being rooted, but no stable Galaxy S rom that works for the other versions I have seen. The leaked 2.2 that people touted a while back only works for a few versions and mainly the international models. Even then it is problematic. A generic 2.2 rom would be more bad than good. Even the Incredible has problems and same chipset as those roms.
2. In regards to root, has anyone rooted the Fascinate and applied any root-only apps and see if they work? The key litmus test would be Titanium Backup. If it works- it is gold.
3. When will 2.2 be released? Samsung is dealing with a bunch of different models to roll out and THEN they have to be augmented with carrier specific content.
Folks, you will probably be lucky to see an official OTA in December. If you do not mind not having Flash or 2.2 until then- cool. I would rather wait and see what happens with the three items above.
Fact is, I would pick a 2.2 version of the Fascinate over the Inc in a NY minute, but the Inc with 2.2 is a better device than the Facinate with 2.1.
I predict that once the luster of a new device wears off, a lot of the folks that buy this device will become impatient for 2.2. The stigma Samsung has for updates will not help this perception.
