Question: Apple ipod nano 4th gen vs. 5th gen I am thinking of purchasing an ipod and I was wondering which one to choose. I really like the nano and see the new version also has fm radio and a video recorder. Amazingly, the prices are pretty close for the 4th and 5th. Any suggestions?
Document: I have both a 4th gen nano and an iPhone 3G. I love them both, for different reasons, and was pretty interested to see what Apple would do next with the 5th gen nano. I was a bit disappointed.Not with the look of it; Apple kept much the same shape as with the 4th gen, and I like the new aluminum finish. The (slightly) larger screen makes watching movies and TV shows a bit better. The cheaper price is welcome, of course.
The 4th Gen Nano was an improvement (except for the forrm factor -- I'm one of the few who liked the more compact form of the 3rd gen). The 5th gen Nano finally sucked me in with amazing new features and teriffic design. Below are the things I really liked and which caused me to shell out for the latest version:1. Better screen.
I don't mind trading off sound quality for convenience. In short, what the 4th gen nano did, the 5th gen nano does a bit better.But the new features left me cold. Video? I doubt I'll ever use it. Granted, given the sensor size, it makes more sense to have lo-res video than lo-res digital photos, but it seems more like a "because we can" feature than anything anyone was asking for. Radio?
It's really not a huge difference from the 4th gen, but the 4th gen was awesome. And this one? It has more features. FM radio and a (low-res) video camera are pretty darn cool. And there's a microphone! I've never even used it, but I still think it's cool! XDThe screen is bigger than the 4th gen, if only by .2". I thought it wouldn't be noticeable, but surprisingly it is.
When I received my new iPod, I was impressed with the sound quality vs. the old 1st gen Nano I have. (The original iPods were very "middy" sounding. )But that is about all that is good with the unit.The new 5th generation is incompatible with everything I own. My car's radio has iPod integration which worked with my original iPod and my friends 4th generation unit, however, the newest iPods are incompatible.
I don't need video -- at least at present, but adding features like this inspires new uses that no one ever predicted (SEE UPDATE BELOW).4. 16 GB. I can fit more stuff in it now (yes, this was available in the 4th gen, but it is a big plus for me -- I did not want to buy another 8 GB ipod.) Additionally, I really don't care about the unavailability of still pictures.
I just think it should come with one.2.) For the 5th generation, they moved the bottom connector, so that some accessories that work with the 4th generation will not work with it.So I didn't think I wanted it and now I can't live without it. For those who don't have an IPod, try it and you'll like it. For those who are wondering if the 5th generation upgrade is worth it, it depends on how much you would find the new features useful and helpful.
If you look at reviews from earlier models, you will see a LOT of people complaing about battery life.If you are not familiar with this style of ipod, be warned that they are quite fragile; drop it once on a hard surface and you can bet that it is going to break. I also do not like the fact that Apple seems to be trying to force people into using itunes (which really bites). It is one of the poorest reviewed music managing programs.
I miss the large screen on the 3rd Generation iPod nano. The new long screen is tiny and not suitable for viewing videos or pictures.The 5th generation nano has terrible battery life. On older models I could run for days without ever charging it. This one requires being on the charger daily and will only last about 8-10 hours at the most. The 5th gen also drains the battery when in standby mode. Older models could last for weeks on standby. This one will die after about 24 hours.
What can I say? I just love my new iPod. I'd already owned a 2nd generation Nano, but it's a whole new experience with this one.Big album covers, radio, voice recorder, video camera (not that I use it that much, but it's nice), mono audio option, whole lotta brightness, great design.Nearly perfect.
Answer: Below is my review, I would go with an unopened gen4!=============================================Last year for Christmas, my wife gave me a gen4 Nano that I absolutly love. This year, I decided to return the favor and get her an ipod for Christmas. I gave it to her early so she could enjoy our Christmas cd's on it. I have to say that while my wife does like it, there are obvious issues with gen5. Fist off, the outputs on the base of the unit have been reversed so the gen5 requires it's own mount to use it on any docking station! Why csn't Apple stick with one body style for the nano. So now all the included adaptors in home theater systems are obsolete once again; makes no sense what-so-ever. The gen5 has a built in speaker that is completly useless! Sound is emitted out of the base of the unit. At best it sounds like and old time transistor radio, only without the volume! The video recoder is very awkward to use with little relivence to listing to your favorite tunes. The genius is still with us, another useless feature if you have an eclectic musical taste. The playlist feature works alot better and is much more fun. The unit works ok and we did not find any defects with it. We did not have any of the click-wheel issues that other reviwers have commented on. For me the bottom line is that Apple has takin a good thing and cluttered it with a bunch of new features. The Ipod classic would of been a much better platform for this stuff with it's 160gb's of storage. All of these features that have been added to gen5 take up precious storage space for your rockin tunes or arias, whatever the case my be.
