I tried a Blackberry, a Curve I think it was, in 2008. It looked nice. I really wanted to like it. At the time, I was coming from a Palm Treo 755; the BB Curve was essentially the same shape and size, with small screen at top and keyboard at the bottom.
I really wanted to like it, and tried to, but in the end, I just couldn't. I didn't like that it wasn't a touch screen (like the Palm and so many other devices), and I didn't like the OS itself.
At the time, I had no intention of getting an iPhone. I'd never actually used one, though. Looking back, I really don't know why I was so much against the iPhone at first. I had a similar problem with getting an iPod, which I had done only about a year or so earlier. Even though this is stupid, I still have a tendency to shy away from the mainstream, or doing what everyone else is doing, or what the "cool people" are doing. But after I had bought the BB Curve and began to realize I just wasn't digging it, I began looking for something else, since I was still able to return the Curve.
I looked at some of the other Windows smartphones and didn't really like anything...I actually did try a Palm Treo with the Palm OS (my older 755 had Windows on it), but didn't like the Palm OS, either. At this time, as I mentioned in the last paragraph, I was always skipping right past the iPhone displays in the stores, but that week the iPhone 3G came out and I said what the heck, I'll take a look, since I'm in the store and there's a line of people that want to buy one and no salesperson available to help me find something else. So I looked...and I liked. And I wound up buying one.
The iPhone isn't perfect. No Android phone is perfect. No phone of any kind, smart or otherwise, is perfect. Each has its own set of strengths and weaknesses. You find the best thing you like and can afford and works where you need it to work, and hopefully you find the thing that's best for you.
