Even though you want to try other phones but for the last time why not experience n9? The best smartphone you can't have & the last of it's kind... Well for me at least my last phone from nokia & I'm a user ever since, never had any other brand... Windows phone doesn't appeals to me so next time around after n9, I might try an iphone but for the mean time... n9 is the smartphone to beat in my opinion plus it's rarity charms me well...
