I bought this player basically because I have become sick of itunes and the lack of flexiblity my ipod touch then ipod classic gave me in organising my ever increasing music library, lack of music file formats, sound reproduction etc. I also wanted a player with better sound quality. The X7 is a large device, but still fits in the pocket, it feels solid in the hand, in the box you get a seperate charger, proprietory usb cable, lanyard, software disc. The device has an external speaker, external volume, power and a single menu button. There are two views to choose from when using the device, their is one with widgets and one with a list view which I currently use. If you only have used itunes to organise your music this will be a wake up call of sorts but personally I have always kept my original folders organised a certain way and I have mirrored that exact file structure on the X7 by dragging and dropping the files onto the device. Their are plenty of media players you can download to help with organising your library, mediamonkey, winamp,windows media player and the included jetaudio software. You cannot make on the fly playlists apart from using the favorites option, you can create them using jetaudio (which gives no instructions how to in the user guide) I found a step by step guide to creating playlists on the X7 at (...)
The UI is not intuitive but I quickly got the hang of it, you can view your files in album, artist genre etc and their is a folder view. Album art is supported but appears on the device enlarged, personally I like how it looks but i have read reviews were some dont like it. The strongest selling point of this device is the sound and the multitude of options to sdjust the sound to your taste, this is a big big plus!!
I haven't really viewed much video on the device but the screen is clear and bright with excellent viewing angles not the highest screen resolution out there but viewing is fine, the touch panal is resisitive which means its activated by preassure and it is suprisingly responsive. Jumping around menus is snappy with no lag.
In short if you are and audiophile and need over 64Gb of space what are you waiting for?!
Update: The best media software to use is mediamonkey which is where i create playlists. Their are simple instructions how to do this on various forums. Again it is not as simple as itunes but personally its an inconvenience I can live with.
