A flash-based Apple subnotebook is coming and will ship in the second half of the year, an analyst said last night.

Banc of America analyst Keith Bachman added his voice to the chorus of analysts predicting such a device in recent weeks. The analyst also predicts a flash-based video iPod.

"We don’t yet know if Apple’s potential move into flash-based notebooks is an anomaly or a trend, and we need to get a better handle on other vendors’ intentions to assess the impact to [hard disk drive makers] Western Digital and Seagate Technology," he told clients, according to AppleInsider.

American Technology Research analyst Shaw Wu last week predicted a flash-based subnotebook, speculating that the product will utilise a specially developed version of Mac OS X, in the same way as the iPhone runs a stripped-down OS X operating system.

Banc of America this week reiterated its 'Buy' rating on Apple stock with a $107 target price.
