I bought the Archos 604 Wifi but returned it due to very slow and crippled Opera an also due to a diffuse screen (the 604 non-Wifi without touchscreen is much sharper and brighter). Opera was very slow and there was no way to display local pages, just to name one of the drawbacks. The PDF-Reader was almost unusable. The 604[wifi] plays and records video very well, but that's all -- too less for me.
