Well I originally switched to Sprint from T-mobile for the original Pre. I held that phone for a year until it was just a little bit too out of date for my tastes and switched to the Evo 4g as a hold over.
I was very much hoping that the Pre 3 would be on Sprint, but sadly I am going to have to jump ship.
I would recommend that anyone who hasn't done so check to see if you have a Verizon discount from work. I do. (government employee 25% discount) I know when I was in the private sector my last company had a similar discount.
I've run the numbers for my single line and I'll actually be coming out cheaper on Verizon once the 25% is applied getting equal service features.
I'm a little unhappy about being in this situation, however. Sprint has generally been a good carrier and my interactions with them have been positive. I also have a thing for supporting the underdog especially because I fear the day when we only have two choices in cell providers like everything else in this country. (quickly approaching with the imminent merger of AT&T and Tmobile) It likely won't be long until Verizon absorbs Sprint. Give it 2-3 years especially with horrible moves like this Pre disaster on Sprint's part.
Furthermore I do not want the Pre to die off. Although Pre support wasn't the best on the part of Palm (not surprising as the company was on its death bed) it was still leaps and bounds better than any android support I have seen. (as I side note I do not blame HP at all for dropping the original Pre... it was a Palm project and was dead before HP ever showed up)
What I mean by that is that android is fractured across various manufacturers. When and IF you ever see a software update is entirely based on how profitable it is to support that phone. The vast majority of the time the manufacturer already has the latest and greatest out and your chances of a software update are slim to none.
With the Pre 3 & Veer HP only has to worry about its own hardware and two phones to support. One would expect that any and all WebOS updates will be pushed to these phones regularly. (after all, where else are they going to push them?) HP wants WebOS to thrive, and that means constant development from this point. I would expect a repeat of the early days of the Pre.... frequent WebOS updates making the platform better and better. Due to the fact only two phones are likely to exist for the foreseeable future these devices will likely get far more support and development than any android user could ever dream of unless said android user plans to upgrade to new hardware every 6 months.
Overall switching the Verizon and the Pre 3 is an all around win anyway I can think to look at it. I have to admit I was somewhat tempted by the Evo 3d on sprint, but for what? A dual core processor? My Evo 4g is plenty fast. I'll have the same version of android and a new layer of HTC sense which will likely NEVER get updated until I put up the cash for the next HTC device. 3d screen was somewhat interesting... but for what? I see myself taking advantage of the 3d briefly as a novelty then forgetting about it.
On the other hand I can get a great operating system that is likely to be supported for an extended period of time. The most frustrating part of Android was the fact it was a "Pre 3" scenario every time a new version of Android or sense came out. When will we get updated? WILL we get updated? Is the phone dead in the eyes of all involved even though I just bought it? You get nothing from the manufacturer or carrier. I'm done with that game.
Again, I'm unhappy to leave Sprint. I really hoped they would survive so that 3 competitive carriers would exist, but they have absolutely nothing to offer most people other than cheaper monthly fees. With T-mobile out of the picture it is Verizon & ATT against Sprint.... and it doesn't look pretty.
