I managed to get 526 photos onto my iPad in around 2-3 hours. I am not really bothered by this because I am not a professional and does not have strict deadlines to meet. What bothers me really is when the photos fully synced onto my iPad, it took a good 2-4 seconds for an image to load. I can successfully slide through 3-4 images that are sharp sometimes, then the next image will have the spinning wheel which takes another 2-5 secs before it gets sharp. This is a pain when I am trying to share the images with my friends and relatives.
And also I noticed that it's using internet connection too when I am viewing the images. I tried turning off data and wifi and it won't load. I thought the images are already synced into my iPad? The whole reviewing process should be fast and smooth like when I am viewing my camera roll on my iPad. Or am I missing something? Someone please enlighten me.
