I think the "Enterprise" era was hugely affected in this new divergent timeline. For the sake of argument let's say the events of "First COntact" still played out the same even without Picard and the Borg involved, in which case the timeline still would look similiar to Prime timeline up until "Enterprise"
With No temporal Cold War involved it means Klanng doesn't crash on Earth because he wouldn't be chased the Suliban. I could see this delaying the lauch of the First Warp 5 mission. I think Starfleet was proably going to go whether the Vulcans wanted to or not which means I could see realtions between Earth and Vulcan not becoming as close as it was in Prime Universe. It also means T'Pol and Phlox never become crewmembers.
Who knows how the chain of events alter from there. Perhaps they become friends with Andorians and they meet the Carddisians and Ferengi and other TNG era races that won't be discovered until much later in the Prime Universe. Personally I don't think Vulcan was quite as important in the new timeline especially since the Vulcan High Council was corrupt and had one guy working for the Romulans. This mght explain why the destruction of their homeworld is basically death sentence ofr their race. Perphaps they become more isolated from the galaxy and thus didn't have as many colonies or whatnot as they would have in the Prime Universe.
With no Vulcans involved that might be why the tech looks different. Perhaps the Vulcans played a huge role in how Starfleet tech looks and operates in the Prime Universe. Hell we don't even know if Vulcan was a Federation member in this new universe. The good news though is Trip doesn't die in this Universe.
