Here is my take for your thoughts. So you know some background on me I am a techie, work with technology all the time and used to support part of my companies sales force and overall mobile strategy. I currently have the iPhone 4, which I switched after being a Windows Mobile person for years.
First, what are your needs? Are you planning on using this solely for personal use or planning some work use on it (by work use I mean work email and calendar). This is critical as companies are just starting to adopt some technologies that work with BB, Windows, Apple, and Droid. You will want to know how your company connects these in this case. For me, my company allows the iPhone, however the connection with the Microsoft environment here is not as strong as Windows Mobile was, or BB is.
If you are going to use it for personal use, what kind of stuff are you looking for, web browsing, personal email, games, photography/video...anything else. These are the main 3 uses. iPhone has the largest number of apps avaialble, although Droid is catching up quick, most apps/games are on both platforms. Web browsing, you are going to want a Droid or iPhone, the BB as you well know just stinks at the web use.
Cameras are heavily dependent on the phone itself, I can tell you the iPhone 4 camera has pretty much put my other cameras, video and point and shoot to the grave (video only comes out when I want to take more than a 5 min clip). Went to Niagara for my 10 year, my wife had her DSLR (which can't be beat) but my iPhone HDR photos were pretty amazing
As for antenna issues with the iPhone, I have experienced it, but since putting the case on I do not worry about it, not an issue.
Glass for iPhone, my biggest gripe was that it was slippery, but again, not an issue with a small case on it. The glass is incredibly durable, as I have dropped mine a handful of times. Dupont makes the glass, called guerilla glass for a reason.
In summary:
- Blackberry - These are going away the app stores for Apple and Droid are far superior
- Droid - Great phones, but dependent on the manufacturer. They have the same challenge as windows, as Google makes the phone, HTC and others make the handsets, so they are not always in full sync with the changes from the OS to the device
- Windows - Still new and growing, app store is starting to build up but may want to wait till some real reviews come out.
- Apple - Large App Store, solid device, best display and one of the best cameras on the phones.
I am not an Apple Fanboy, actually quite the opposite, as I own no Apple computers and it took me till the 4 to buy an iPhone, even an iPod I was reluctant to buy at first, going with the Dell MP3 initially. In general, this is by far the best device I have ever owned for a smart phone. (4 palms previously, 2 Samsungs previously). My wife has the 3G, which is slow and cumbersome, the 4 is non of that. I play games, have work email and calendar synced to it, use it heavily for pictures and video, and the occassional web lookup (this feature helps me greatly as I do not have to get the computer out many times cause it is just that good.)
Hope this helps.
