Game art for my project codename Battlescar (because I haven't thought of a proper name yet!).

Old thread - http://www.wayofthepixel.net/index.php?topic=11587.msg120144#msg120144

Hi guys. since recently becoming quite addicted to pixel art, I'm really wanting to be able to do this on the go instead of being chained to a desk.
Also I would like to say go have a coffee somewhere and do some sprites.
So I'm looking to get some feed back from u guys who use tablet pcs which are good and bad?
Where I live in brisbane australia it is really hard to find these in stores to see before buying so I'm trying to find out what is the key requirements.
I don't want to spend more than is necessary to run photoshop without lagging too much but I am also tempted to spend up to around $1000 if it was much better to work on.
I don't plan any high resolution stuff though sometimes I end up with quite a few layers.
I don't care if it runs win xp or win 7.

I realise it needs resistive/pen input and am wondering if pressure sensitivity is a big plus for pixeling?
I see that some models also have capacitive multi touch which seems great I can zoom in and glide around with left hand while penning with the right but I wonder if anyone has experienced this with photoshop and knows if it ruins the square pixels by making it blurry or odd shaped "crusty" pixels because that would put me right off.

I heard the motion brand is quite good and lots of features but what brands do u guys recommend?
Also if anyone is perhaps selling a decent one that works good then I could be interested.

Hey guys I'm new here and inexperienced with pixel art.
I've been trying to work out how to draw rocks to use in my action-rpg platform game and this is what I came up with last night.
No special features, just plain old repetative rocks but its the first time it hasn't turned out totally crap so I thought I would post it 



I'm just using the image editor in Game Maker 8 Pro without any preparation sketches.
Any feedback or handy info for a noob is welcome.

Also I'm generally really hopeless with colours so if any of you pros have some helpful info, tutorials etc on building palettes that would be great   
I have trouble with how to get nice colours where for example green grass might have more blue in the shadowy bits and more yellow in the highlight for example, is there a technique to this sort of thing or do people just do it by eye?
Another example is how to make a stone block look like it has multiple light sources of different colours.
And if there is cool techniques to add clear, shiny water (rather than hardcore blue) trickling over rocks.
Anything along those lines is helpful
