I have a 32G Iphone and have never hada problem with space. I'm hoping to get an Ipad for Christmas, but I'm confused on the size. I really don't want to spend the extra money as I want to get he 3G too.
Tell my why I would need the 32G over 16G
Thanks!
Between the 16,32, 64 models, there is no difference outside of storage capacity. Talking about the same screen specs, battery, cpu, and so one. Screen could vary slightly because it could be made by different vendors, but they are meant to meet the same specs Apple requires of them.
So it comes down to storage. How much storage do you need? Or shall you ask yourself, how frequent you plan to upgrade your ipad and how long you plan on keeping the current one? --> for example, if you don't anywhere near 16GB now and don't see it by the next release of iPad --which you plan to upgrade too in an annual basis, there's no need to get the larger capacity now. If you ever get close to the max. capacity; then you know to get the one larger next upgrade.
On the other hand, if you plan on keeping the ipad for several years before upgrading, then you should think about future-proofing your capacity needs. I would estimate the number of years you plan on using it before upgrading; then look at your capacity usage else where over the last year or so and see the rate at which it grows. Get an estimate month-to-month or year-to-year and compound it over your estimated years and see which capacity is enough.
Lastly, if you plan on using the ipad to watch movies on the go while traveling for long periods of time... then ask yourself what is the maximum length of travel where you would not be able to sync your ipad to your laptop; and how much videos do you plan to watch in that period of time. Subtract the time where you would not be able to use the equipment (in-flight after the door is shut until you are in midair...) and multiply it by the average movie size being around 300MB per hour video. The 64GB would probably get you 120 hours worth of video capacity before you need to sync and update your next 120 hrs worth of videos. -- Possibly useful if you plan to travel with a ton of video and don't plan to bring along a laptop. You'll still be limited to the battery-usage life of the ipad (about 8-10 hours per full charge).
I found most apps, email, (everything else) not taking that much space. Its multimedia that will eat your space, and this would be the factor if you like to carry a lot of these with you.
the longest time away from a computer I've been was to my honeymoon for 2 weeks. I sync all my unwatch tv-shows and movies to my 64GB ipad2. I barely watch 1/3 of it, but it was nice to have access to it. In normal daily life, I only use half of 64GB, syncing only the last 10 oldest unwatch shows.
