i think the 4s was disappointing because many people were expecting an iphone 5... but, calling it a joke is kinda calling the whole industry a joke... you're asking tech companies to reinvent the wheel every year? i think that's asking for a lot. RIM definitely isn't doing that either... all their phones are just the same phone just made in a slightly diff form factor and made with hardware upgrades... i think the 4s is just that, but in the same form factor. I think it is actually smart of apple because it cuts production costs down, and it allows them to focus their energy on one product at a time instead of trying to release a billion models. It's just like cars, same form factor for 4 or 5 years with tweaks and upgrades every year. I'm not saying you'd buy a new car every year, but really, i don't know anyone who'd buy an iphone every year. I only know of your brother. But at the same time, there are idiots who buy a new car every year as well but they have the money to do so. smart phones also have a shorter practical life than cars, so when you upgrade a phone once every 2 or 3 years, it's like upgrading your car every 8-10 years which many people do or even shorter. Heck, you went through 3 cars in 10 years? and they were golfs/gtis every time. I these terms, i'd hate to break it to you, but i think you're probably the vw fanboi equivalent...
personally, i think apple is doing well because it's doing a better job catering to its consumer. Sure, they market very well, but i think the reason why they don't go back the the drawing board with each iphone design is because they know what works and what people are familiar with and what people want them to improve on. Adding multitasking support in the 3gs and onwards, facetime, tethering, among other improvements were made because of the public outcry for it. And embracing the app world like you said is just another example of how they're catering to their potential consumers. They i think they're doing a good job putting an ear to the public. They may not be the ones who invented the touch screen, and i never said they were, but you can't deny that they were the trailblazers who took the smart phone to a whole new level with the touch screen.
Honestly, i'm no fanboy of apple even though you may think i'm as evil as your brother. i just can't deny that the iphone offers more than blackberry products for the general public. The only real reason why i'd buy a blackberry is if i want that keyboard like you said. But i don't. sure, it's easier to use if you're texting, but after you get used to the touchscreen keyb, it's not so bad. Most people i know who have a bb, say that the reason why they have a bb is the keyb... so if you like the keyb, the more power to you. I just think all the other stuff the iphone, or even an android phone can do is so much more advantageous than any bb phone.
