酷狗

try google pinyin.

for PC, i recommend "Google pinyin"(http://tools.google.com/pinyin/)
for Mac, "Fun Input Toy" would be the best choice(http://fit.coollittlethings.com/?page_id=3)

you can use your own operating system, like Windows XP, at first enter "Control Panel", then click on "
region and language option", then choose "language", click on "detaisl", then click on " add...", and choose "Chinese(China)" in "input language". now you can use it.

i recommend tencent QQ http://im.qq.com/
