A bit late to the party, but may have some useful info!
Have been looking into this for the past few weeks, as my Lenovo X60t is on its last legs now, which isn’t great, especially if you just want to have a mess around sketching in an evening. My partner has an iPad, but I have never really gotten to grips using a stylus with it due to the lack of palm rejection. What I am really after is a windows 8 tablet…
After a lot of digging I found that the Samsung S Pen is indeed a wacom stylus, just rebranded. This means that pretty much any of the new Samsung tablets, as long as they come with an S Pen, should be fairly good with sketching. The problem then becomes software, as the android version of SBP is fairly paired down in my experience.
The Samsung ATIV Smart PC Pro comes across as a bit slugish in the video that @Travisimo posted, but this is only the standard version using an atom processor - in my opinion the atom is a bit slow to handle SBP with lots of layers. They do however have a pro version, which has increased ram etc. This is currently going for about £1k GBP. That may change things.
It sounds like a real solid contender in my view, but the reviews of the accompanying keyboard are rubbish - so it would have to be a sketch only device rather than a laptop that you can sketch on.
The Fujitsu T902 and its counterpart that splits apart both have wacom enabled stylus’, however despite good reviews in the US, there are no dates on when it will appear in the UK, and like mentioned before, it isn’t as nice looking or as easy to pick up and sling around.
My main question at the moment is regarding the MS Surface Pro - some of the digital arts forums have posted a response from Wacom saying that they do make the screen on the Pro version - would that make it a contender? Has anyone had any hands on experience?
