Of couse not. I used iMac before and I really enjoy the stablity, speed, and cool GUI. And I wrote documents through its office kit, you can save as word, html, or rtf format. It looked exactly same as in Window machine.
But I don't recommend you to buy one. You can't find a lot of 'cheap' software for iMac, and its not easy to be updated.
新的 iMac 很酷，很动心。哪位 DX 帮忙分享一下买 iMac versus 买 PC? 因为价格不低，所以不太敢轻举妄动。
