Where is the mobile photography workflow?

On my Workstation at home I use Adobe LightRoom for all my post-production editing.  Ideally it would be great if I could work away from home on my photos without adjusting my current workflow.  The choices are simple.  I could either go for a full fledged version of LightRoom running on a PC or Mac Laptop or a Android or iPad tablet with an equivalent application like adobe Revel.  

Hardware

When it comes down to deciding on hardware the first deliberation is weight vs cost.

Device	Type	weight	Cost
iPad 2 - Wifi 32GB	Tablet	613g	£479
Asus Transforme Prime 32GB	Tablet	586g (Tablet only) 1123g (with Keyboard Dock)	£495
MacBook Air 11" 64GB	Laptop	1008g	£849
Asus ZenBook 11" 128GB	Laptop	1100g	£849

So as we can see with the laptops you are doubling the price and the weight.  On the plus side you are getting a powerful machine and get to use a full copy of Adobe LightRoom.

Tablet Software
While tablets are becoming widely available there is still a noticeable difference in the quality of applications when compared to the former laptop.  While Adobe's Photoshop Touch offers nice functions and features it still has limitations in photo resolution and format that would not make it part of a workflow.  Adobe Revel (Formerly Adobe Carousel) is currently only available for Apple products and is the first table app that I have seriously looked at.  The first thing that caught my eye was its LightRoom photo processing capabilities, integration and unlimited cloud storage.  This however is not a cheap option with a monthly fee of $5.99 (annual $71.88).  Other aspects that disappointed me about this software was its current lack of support for RAW files and its inability to transfer images from a cameras memory card to an iPad.  This means that if on a shoot I would have to wait until I accessed a workstation before I could manipulate the images on the table.   There may be a way around this by using a multi-card reader adaptor and would need testing, but this is a large oversight from Adobe as I would want to be able to start my work on a tablet straight away.

If I was Adobe...
It was with this thought I came up with my ideal photo workflow app for a tablets. Lets call it "LightRoom Mobile"
The main aim of the app would be to process the first steps in my post shoot workflow like the catalogue, flagging, rating and then basic processing of white balance, exposure, saturation. These processes do not require large CPU power and I don't expect a tablet to do everything that LightRoom does.  So far this is exactly what is available with Adobe Revel and what I love about software. But lets look at what it lacks in upload and RAW support.
The main question I asked myself was this. "Do I need to work on RAW images?"  "I do" I thought as I want the best available quality on all of my photos. After some thought I rephrased the question. Do I need to start my workflow with RAW images"  and for this the answer is "No".  
Let me give you a scenario for example. Lets say you are out and have a wi-fi enable camera or maybe an eye-fi SD card. With my Nikon D7000 I have two memory card slots and can shoot in RAW+Jpg and send all jpg images to an eye-fi card where they would be instantly transfer on to a tablet device while the large RAW images remain on the camera. After the shoot I could pick up the tablet and instantly view, catalogue, flag, rate the photographs using only the jpeg files. I could also start to crop, white balance, exposure and maybe a few other tweaks that the tablet CPU and jpeg files can manage.
Now I have edited all my jpg and completed half of my workflow for that project/assignment; Hurray! But wait!! I don't want to do this all over again with the RAW files. What if the application enabled me to  sync all the amendment that was made to the duplicate jpg's on the tablet with the RAW images from the camera once uploaded to a PC/Mac. I would then have all my RAW files calalouged, cropped and edited and ready to continue the remainder of my workflow on a PC with the grunt for the retouch work.

The waiting game
With this all off my chest all I can do is wait for light laptops to become cheaper or Adobe to make the tablet app of my dreams.  Until then I would like to know what you think and if you use laptops or tablets in your editing workflow.
