Personally I wouldn't go the ipad route when there are so many tablets around that you can nab that will offer so much more. The stylus options are pretty bad and you won't get the same pressure sensitivity as you would with a wacom digitizer. What I ended up doing was picking up a refurbished hp elitebook 2730p for around $200-300, and threw in some extra ram, and bam. Full laptop with wacom support that you can fold into a tablet or use like a regular laptop and run SAI, Photoshop, any and every program you're used to. With the ipad you're restricted in what apps you can use, how much space you have and how easily you can transfer to your main computer.
Honestly the processor has been managing pretty darn well on the thing since it's a full powered dual core so still manages better than some of the under powered atoms you'll find. SAI painting and inking up to 350 dpi is smooth, and Photoshop's been doing well as long as I stay away from the 500 pixel brushes, which does cause some minor lag. The fact that you can stick a SSD and 8 gigs of ram in it means that despite it's age, you still get a machine that's beefier than a lot of the slate form tablets. You really can't do much better for the price range. If you can afford a little more, I've heard good things about the asus e121 but I think those are still kicking in the 500-600 range.
If money isn't a real issue, you have the new samsungs, and if Microsoft gets tired of playing chicken with adobe over wintab, the Surface is a *beast* of a beautiful machine for 1k. For a little more than that, Levono Helix is looking rather insane but it's not out yet.
No, you need a computer for a wacom tablet. The Tablet is just like a fancy mouse.
If you want to draw anywhere on paper and then upload it later you'll want something like this: [link]
Or you can get a tablet with a stylus. Microsoft, Samsung, Apple, and a fuckton of other people make tablets that would work. Some come with styluses and some (namely the iPad) require 3rd party styluses.
I'd say a Galaxy Note 10.1 or a Microsoft Surface Pro. I personally would go for the Surface Pro but it's a bit more money.
Or, realistically, I would get myself an iPad and a Jot Touch but the Touch isn't out yet and I think the screen on the iPad is worth any amount of built in stylus fanciness... but that's all for you to decide based on what you want to do
I don't see how they could, it's just plastic on hardened glass. I imagine it's just people scratching the screen and blaming the pen. I mean, normally iPads get tiny little scratches if you're careless.
oh it could scratch very easily from the pens. Although the widespread use of Gorilla Glass has certainly helped this matter, most Pen displays; Cintiqs and Tablet PCs are designed for Pen input, so they're manufactured to have better scratch resistant screens. That being said...its still possible for this displays to still get scratches. I just got a 21ux Cintiq a few months ago and got my first scratch just a few weeks ago. The pen nib could wear down with time and get sharper...but also accumulating dust or grease on the screen (very little that you can't even see) could cause scratches as the pen draws on it.
In the case of the Ipad....which of all devices was never designed for any remote pen use.....using a 3rd party pen...that's a risk you're just going to have. The Gorilla Glass certainly helps..but only so much. My old Ep121 tablet PC has Gorilla Glass and I got a few scratches on it.
My understanding is that the problem with the Jot isn't that the plastic scratches directly but that it is more inclined to attract and to pull dust across the screen than other stylus designs or bare fingers.
