Hi Peke!
OK, here´s my short review of the Vibez:
First I have to say that this is the best mp3-player I ever had, and I had before the Rio500, 800, the Rio Chiba and the Rio Carbon.
First of all I bought if because of the DJ-Function that works very well for me. So on the road you can play your favourite Music, New Music, forgotten gems, Music of a special Yeyr, random Mix, etc.
That´s very, very cool, especially if you have a large music collection.
Also the sound is the best I ever had, and for me, it´s just loud enough.
You can also browse by folders, if you want.
Bookmarks are named Sessions on this device, and you can auto-name them and update a Session.
The Screen is crystal-clear and bright, but if you´re outside in the sun it can be a bit unuseful to read, but that´s with all kinds of displays I think.
Because you can choose different color-schemes you can switch to black and white and so it is best readable in the sun.
There are some screensavers (nice, but not necessary I think), you can show Album Pics, and a Peak Meter.
You can add a Radio Card (for such a small, portable device I think the sound of it is satisfying), a docking station and a cable remote. The latter two are not available yet but are announced for June.
The Accu is user-changeable and lasts for me about 10 hours, but I switch around tracks very very often so this is energy consuming.
You can connect it via MTP or MSC (MSC via Registry-hack).
You can also delete tracks on the device and record via line-in or with the build-in Mic.
But there are also some minor flaws about this thing:
The sennheiser Earphone is not the best, I use a Creative EP630. And this one has a higher impedance, so you can hear sometime hiss if the display goes on or the hdd spins up. So you better use earphones with the right impedance!
Another thing is that the playcount counts after the 5th second of playing a track - very annoying I think!
The Click/Scroll-Wheel is very very good to use, BUT If you use the Bag (Accessory) you cannot turn the wheel so some functions are hard to use like in some menues you cannot scroll down or up and you have to pull the Vibez out of the Bag.
Also a shortcut for "Update Session" and "Delete current Track" would be cool.
But all in all a very nice gadget - smaller than you think if you see the pictures of it- and very convenient to use. It does not look cheap and seems to be high quality, I would buy it again.
But I also hope that some minor things I mentioned above will soon patched with a new firmware!
