well my reckoning is that nokia n900 is the best at the moment when it comes to a mobile computer cum smartphone,agreed with the drawbacks lke most apps dnt have potrait mode etc but picture this;
-only mobile with ability to multiboot maemo,android froyo :n900
-only mobile in hich i can change cpu clockrate btwn 600 to 1150 mhz seamlessly
-only mobile to give full web access and runs my fav chrome browser with cool extensions
-only mobile to run a desktop linux ie easy debian like a virtual machine with maemo
- only mobile that...puts my intel core i5 proce laptop to shame sometimes with it running abt 60 apps multitasking ie 30 apps + 30 widget apps in 4 desktops with all desktops running different live wallpapers...need i say more...

cheers
