Apple's new iMac has generated positive response from the investment community.

Wall Street investment analyst Piper Jaffray this morning welcomed Apple's release, saying it should create greater-than-expected demand and improve the company's share values.

These comments were later echoed by Standard & Poors analyst Megan Graham-Hackett, who estimates fiscal 2004 earnings of 64 cents per share on Apple stock, and views the shares "worth holding".

Apple shares stand at $34.51 - up 39 cents - on pre-market trading as this story goes to press.
