It is just a cosmetic feature. People are still using Windows XP and are not bored with it. Like any computer whether a PC or Mac, you tap into one of the icons and it launches an app. How is a mobile OS really any different than a desktop one? The point of these devices is for productivity or entertainment.
Jailbreaking can be your best friend. Even then, you will get bored of it just like if Apple gave us an official refresh. Who knows what a resource hog it will be? You will get bored of anything if you happen to stare at it everyday for the last four years. I gotta a Palm Pixi Plus (AT&T model) for $60 brand new off Craigslist that is keeping me entertained as a backup phone. Really solid phone for the price even though it lags. You do sometimes appreciate iOS more, but at the same time, I also like the many ideas that had Palm had with webOS including the very unobtrusive notification system. If you have a disposable income, try collecting different smartphones. Variety is the spice of life.
