This is a notebook review site, and the Sony VAIO VGF-AP1 digital audio player is not a notebook by any means, but interestingly enough it does come from the Sony computer division rather than their consumer electronics division.
Since the VGF-AP1 has a 20-40 GB hard drive (as large as some notebook hard drives), has a color screen for viewing images, has a touchpad like navigation system and provides multimedia entertainment it does sport some notebook like features.
But think of the VAIO Pocket more as a complimentary product to your VAIO PC for enabling you to take all the MP3 music files you have on your notebook in your pocket with you.
The QVGA color screen is very bright and has a fantastic color display for showing such things as album art, track listings and of course navigating through menus to select songs you want to play or images you'd like to view on the screen.
With 20GB -- 40GB of storage on the VAIO Pocket there should be plenty of extra room for the digitized family vacation album from the past decade.
Before the latest firmware update, the VAIO Pocket required music files to be converted to ATRAC3 audio format, the software provided with the device automatically made the necessary file conversion when moving MP3 or WMA files over to the Pocket Player.
The headphones that came with the device were standard rather cheap Sony headphones, so you should use something you have that's better or invest in a decent pair of headphones to do the player justice.
The VAIO pocket comes with what I call a non-wireless remote to make control of the device easy when it is stowed away in your bag or pocket.
