Regarding the Pre "review" in BGR. It was a pre-production unit and did not appear to have the final software installed. Plus this "review" did not say anything about the actual use/quality of the phone. I would not base my opinion on the Pre until the real reviews come in.
The Pre is a big gamble for Palm. There was an article a few weeks ago about companies that will not be around next year and Palm was included. As a user of Palm products from way back, I hope the Pre is everything they need to survive.
There are still quite a lot of Palm users who have invested a lot of money on 3rd party apps. When the Pre was introduced it was basically stated that there was no way to run the old apps. Palm listened to their customers and now an emulator called Classic from MotionApps will be available at launch. This will give the Pre access to over 30,000 apps. You can argue for/against the idea of having an emulator available. I just know that I am glad Apple included Rosetta in OS X so my intel Mac could run apps without having to wait for the developer to make compatible versions.
I am sure a lot of developers would prefer an SDK that allows full access. From what I understand the SDK will not be available until August so I would hold off judgement until its out. All of the apps that are installed on the Pre at launch are written using the SDK and they look pretty good. I also believe that right now some of the bigger 3rd parties are getting access to an SDK that allows full access to the Pre. I am pretty sure that the Classic emulator could not be written without it.
The Pre currently has a physical keyboard. The iPhone does not. Some people prefer physical keyboards and some do not. I still miss Graffiti

. I have read rumors that there may be the possibility of a virtual keyboard released for the Pre. This would give the Pre the best of both worlds.
Synergy looks interesting but right now I do not know how I can sync my data on my Mac to the Pre. I do not really want to use the cloud to store all of that. Also I do not know how individual programs will sync their data. Will these companies have to setup their own cloud so customers can sync their data? Will I have to have a separate desktop program for each? That would be a bad idea having to run multiple programs to sync data to a phone. No real information on how that will work.
I think the term "iPhone Killer" is somewhat of a poor choice of words. When its used, I think it puts iPhone users on the defense. Without a doubt the iPhone was the 1st phone that got a lot of things right. The cell phone market is hampered by the carriers and the limitations they put on phones to nickel and dime users not to mention contracts and poor customer support and exclusivity agreements. Any time a new phone is introduced that brings something new to the table should not be immediately dismissed because its competing with an iPhone. Up until a year ago I could not even consider an iPhone because AT&T did not offer service in my town

.
TLDR: Wait about a week for the Pre to be released and real reviews come out.
