The Differences Between Apple iPod 2nd and 3rd Generations
To date, the best hand held computer that allows multi tasking and rapid Internet Wi-fi access is the Apple ipod phone. However, many want it this ability without the phone. Enter the Apple iTouch, which is the iPhone minus a phone and camera. I have tried the Nokia 800, 810 for a small computer to wifi and get online. They work fine BUT for the slowness of surfing, which in computing is a death kill. We are so use to instant, or at least within 20 sec, of web access. If the device takes a minute to change or connect, it is too slow. The Garmin Nuvi 295 GPS is much better, has a built in camera, wifi and GPS. It is faster for web access yet can be slow depending on the site. The camera is good and for email, great. Yet, the screen is a bit smaller than the iTouch and remains much slower to web access (we are talking seconds) enough to irritate you, which is why the iTouch remains the best handheld computer.
The differences between the 2nd and 3rd generations of these devices are mostly minor with the major difference is the internal processor. The 2nd generations use a 533 mhz processor while the 32 gig and 64 gig memory models use a 800 mhz processor, which is 50% faster. That alone makes it worthwhile to buy a used 3rd generation. However, buying a 3rd generation ipod with only 8 gig of memory will have the 533 mhz and only 128 RAM.
The 2nd generation had the 8, 16. 32 gig memory, while the 3rd Gen had 8, 32, 64 gig. The 2nd Gen had 128 RAM in it, the 3rd Gen had 256 RAM. The 3rd Gen has bluetooth capability while the 2nd Gen has none.
All other specs are minimal differences.
