These 2, or at least mobiblu are interesting - but as gadgetry only,
while ipods and zens remain consumer goods bought for their functionality and design.
Mobilblu is so small that it can only show file name, forget id3 tags, playlist etc. Paired with poor battery life and proprietary cable this product is design over features and functionality in my opinion. No go for anyone that actually reads reviews before shopping
I guess mp3 manufacturers should focus on creating new things to challenge, say, sony-ericksson mobile w950i with mp3 playback and 4GB memory instead of adjusting size to feet palmsize of my 2 year old son.
