Using this game on the mac with safari, and a real mouse works great
on the iphone it is much harder, unless you have little skinny fingers, if you tap the jewels, the screen can magnify, then you have to wait for the resolution to render before you can make a move. I think this is a wonderful start, and encourage all developers to continue their work. I am just torn, apple has made their iphone safer from bugs (ask and palm user) but yet makes games like this much harder. On my treo you install an app, like bejeweled, and it is yours for when YOU CAN'T get online. you will NEVER be able to play a time waster game while on an airplane.
sorry for the rant, by the way, once you get used to the touchscreen keypad, you can type pretty fast, i just impressed myself
