RUNCIMANCONCEPTS  I've been a SBP user since version 2. I was really glad to see the release of 2009 when it hit. But hard to explain my excitement when I got my hands on the latest 2010 release.

The new tools make the sketching process much more precise without being overbearing. Ellipse? How did I live without that. The controls are clean and intuitive and it performs better than I would have thought. Straight edge is also a clutch addition, as now more than just my horz/vert lines will be perfectly straight.

I've also been using Alias for a couple years now, and seeing the texture brush added to this low cost app, is almost unreal. My custom brush library is getting ridiculous.

It's official. SBP 2010 is my only sketch book. (Weird to say after so many years of remaining loyal to the #2 HB.)

STARRSHAW  Sketchbook Pro was already impressive with its easy on the hands and eyes user interface, its perfectly smooth drawing tools that feel as natural as pencil and paper. Now! With this update! Its even Better! Texture brushes that make speed painting real speed painting!! And tools no other CG graphics application has that make this a 5 star app! Its well worth more than its price!

MILOWERX  Sketchbook Pro (SBP) kicks major butt. Whether you're a seasoned pro or a digital newbie, the simple-to-use interface will have you up and drawing in 10 minutes. Let's see you do that with Photoshop! One other reviewer suggested that ArtRage was cheaper so you should buy that. I disagree. ArtRage is a fine tool but all it does is paint. Anyone who can paint can draw but not everyone who can draw can paint so I would suggest that you get SBP instead because it allows you to draw and paint. ArtRage's pencil tool is terrible whereas SBP's pencil tool is without a doubt the closest thing to the real lead and rubber original you will find on the market. Painter, Photoshop, Paint Shop Pro, Artrage, Twisted Pixel and any other graphics app out there can't do pencil well. The only other one that comes close is Scribble and that's not advanced enough to warrant using it professionally.

SBP does it right out of the box... and the new version is even better than the previous versions because it now has a ruler and an ellipse tool as well as custom brushes with which you can create textures to draw with and save.

All in all if you want to create amazing art with your computer look no further than Sketchbook Pro 2010. It's easy to use, robust and I dare you not to fall in love with it's interface.

D@VE  This is without a doubt (IMO), the closest you can get to drawing with a pencil on the computer. Since Autodesk revived Sketchbook Pro, they've added some amazing tools and honed the compatibility with files like psd. Coupled with a good tablet/tablet PC, you can't go wrong. Excellent software. Highly recommended.

DA1LEGEND  Ever since R1 in version 2009, Autodesk has changed the licensing system back to the classic serial number. I find that much appealing because you don't have to deal with all the registration stuff, and find yourself lost in the mist of all that junk.

This preview version is awesome. They certainly took into consideration alot of what a digital artists needs. All the new improvements and the high quality line strokes helps to create an awesome illustration.

THOTH  I was really tempted to buy this program. I bought ArtRage instead, for the following reasons.

1. Most important to me, Sketchbook Pro uses a network-based phone home system to register software keys. That means you need Autodesk's permission to install the software; your computer contacts their servers over the network and ties the key to your specific computer so you can't install it anywhere else. If you change computers a lot as I do, that simply won't work. Not only that, it invades my privacy and it's just rude to treat paying customers like thieves.

Let's not forget that pirates will not have to worry about this copy-protection. They have cracked it. It overwhelmingly penalizes and alienates paying, good customers, with no valuable return to Autodesk.

2. I didn't see a way to draw simple shapes like a square or an oval. What's up with that? I would expect a sketch program to support basic shapes and stencils. ArtRage does. (Feel free to correct me if I am wrong on this point, I didn't do an exhaustive survey, but with some effort, I couldn't find simple shapes.) Also, where is the text tool? I'm sure there must be one somewhere and I'm just missing it, but obviously my efforts could not reveal that feature either.

3. The program costs four times more than ArtRage.

Having said all that, the program per se is not bad. It's got a good selection of brushes and drawing tools. I'd have to say as a program per se it is flawed, but quite good nevertheless. But given its offensive copy protection, its lack of some basic features, and its much higher cost compared to the competition, I simply cannot recommend it.

By the way, if your needs are very simple, you might try Scribble. If you need real power, that app is not for you, but if you just want to do some simple drawings, it might be great.

DA1LEGEND  I'm glad that Autodesk revived this product. It's a great and fast illustration and sketching software. Simple and Clean with awesome stroke quality. Good stuff.
