Pros WiFi IS the FUTURE! PORTABILITY IS the FUTURE!
Cons Opera Browser is a BIT of a DOWN. Blue-Tooth would have been "morebetta."
Summary I actually bought both the 604 wifi and the 704 wifi. Why? As a cross country bicycle rider...The Souther Tier in 2008-9 and then New Zealand and next Ireland. I need the portability FACTOR in everything I do. The 604 can capture what I need with the helmet camera and I can offload it onto my 704 for future cut & paste. I personally LIKE the 704 for DVD entertainment. I wish there was a company which allowed me to pay for avi download of MOVIES to my 704. Perhaps soon in the not to distant future! I do NOT use either of these for my MUSIC. I use my Sansa Express 2.0 GB + 1.5 GB MicroSD chip AND I have Customized over 1200 tunes where is the MUSIC-of-My-Life on a chip not bigger than a finger-nail..Go figure! Fortunately, I have my own CD Original collection of over 200,000 CD's. (A past business venture) It doesn't get better than this until tomorrow! But for now I would strongly suggest the 704. Why not the 705! Exact same footprint for more $$$. LOOK AT THE SPECS! I retired 13-years ago at the age of 48 and I do WATCH my pennies. How else can I afford to buy such GREAT ELECTRONICS? You should see my Hi-tech bicycle I had handmade in Utah last summer..Not to brag, but technology is GREAT and so is life! Hope it's the same for you too!
Pros Great Resolution
Cons A little Bulky
Summary Great resolution in movies. The sound from the headphones included could be improved. Overall, this is a very good player.
Pros screen size, abilities, and hdd size
Cons takes tinkering to configure just right add ons yada yada
Summary After all i do love this it gets me through long stressful days of work and can even put on my treadmill and watch while im running remote is a sweet add on only real issues is the add ons are dumb and there is no programs that would have put it over the top
