For photo editing my needs are basic. It's just the graphic design I'd like. Until now I've used illustrator on my Mac. I'm sure there's no similar programme for tablets but what's the best for the iPad?
Why is Nvidia an oddball?
Thanks for answering, just want to know all so I can weigh up the pros and cons
Basic photo editing will be just fine on the iPad, especially the Air. The added size and 100 percent color gamut will serve you well. Avoid the Mini for the smaller size and inaccurate colors. There isn't any way to correct the washed out reds and purples on the Mini-it's a limitation of the hardware, and should certainly scare off consumers looking to do accurate photo editing.
Nothing on the iPad is going to have the power, ease of use, and versatility of a desktop program like Illustrator. Tablets just aren't geared for that type of productivity yet. Believe me, I have tried to make that work. My old PC does that much better using an aging version of CS4 than my iPad ever will.
The Nvidia has a couple things going against it. The aspect ratio of the screen is 16:10, rather than the 4:3 of the Air and Nexus 9-meaning it is tall and skinny rather than square. I find that to be far less useable for everything from photo viewing to Internet browsing. Too tall when held portrait style, and too short when held landscape style.
Also, the Nvidia has a lower resolution, so you aren't going to get the same crisp image that you'll see on the other devices. The IPads and nexus 9 are 2048x1536 vs 1920x1200 for the Nvidia.
The Nvidia tablet is targeted towards gamers, and runs a non-stock version of Android. When it comes to Android devices, I always opt for the stock OS of a Nexus device. Android is fragmented enough as an OS without adding a custom skin and bloatware that usually is on these units. That's why I say oddball.
Also, the resale value on Android tablets is low compared to Apple products. Just another thing I'm throwing out there.
Don't get me wrong, I have had a few Android phones, and currently use a Nexus 7 (which I absolutely love) as my "beater" tablet. I just think that the iPad Air is the front runner right now, by a long shot.
