I've been using it for just over a week now, and have not once regretted buying it. People dub it "A Big iPod Touch". They're right, but that's the beauty of this product! - The larger screen real estate allows developers like myself to create much more immersive applications, and games are incredible on it. Youtube is a great experience on the iPad, and watching movies and TV Shows is equally as enjoyable.
Internet browsing has been faultless. I have never actually been to a website on my iPad that expects me to have flash to use all the content - Most websites now have converted their content to MP4 (Playable on the iPad), and with the new safari, the content plays inside the web browser - no need to use all the screen to watch it (although it is still possible to do so). The only problem I've had is that some websites haven't updated their sites to support iPad. For example, visiting a website can bring up the "iPhone" version of their website. This is the responsibility of the website owners, so this isn't a drawback of the iPad.
I've downloaded the iWork suite for iPad which works flawlessly, and the keyboard is really easy to type on!
32GB is plenty big enough for me, I've got pages of apps, 40 TV Shows and Movies, Only a few songs though (I haven't put my library on yet), and still yet to reach the 25GB left mark.
The actual capacity of the 32GB iPad is 29GB, leaving 3GB for system resources and software.
Wifi worked straight out of the box, although for improved Wi-Fi access, you may need to download the software updated through iTunes, as they have fixed some things with Wi-Fi disconnecting occasionally.
Otherwise, this product is one of the best Apple products I've ever owned - and beats a netbook hands down.
