We have the black bezel version in-house, though Apple also offers the iPad 2 in white trim. If you spring for the white model, it's just the bezel that's a different color; the back cover is still the same aluminum. One potential pitfall of investing in the white model is it could potentially distract your eyes from the screen and make it appear less bright than it really is. This is the reason you don't see TV makers slapping white bezels on their HDTVs, though we don't want to overstate this with the iPad. We have seen the white iPad 2 in person, and while we didn't perform any in depth testing, it wasn't as though the screen appeared dark.
It's also worth mentioning that if you are considering the white version but fear you'll gunk it up all the time with your dirty fingers, it's not going to show your Hot Pocket remnants any more than the black version will. There's a scratch resistant glass panel that covers the entire front, including the bezel, and that's what you'll be dirtying up, not the bezel itself.
Connectivity options is one area Apple intentionally locks down. Still 'missing' from the iPad 2 is a USB port or expandable storage, such as a microSD card slot. The way Apple figures it, if you want more storage, opt for a higher capacity iPad to begin with. That just doesn't add up to us and limits the devices expandability, no matter how you slice it.
You'll find Apple's proprietary port on the bottom, which is the same that's used on the iPad 1, iPod touch, and iPhone. Through this port you can add functionality, like a memory card reader to transfer photos from your digital camera. Apple also now sells a $39 digital AV adapter so you can hook your iPad 2 up to your large screen HDTV via HDMI. Doing so will mirror whatever is on the iPad to your TV in up to 1080p, though movies are limited to 720p. The adapter also pipes digital audio to screens that support it.
On the top of the iPad 2 sits the power switch and 3.5mm headphone jack, and on the upper-right side you'll find the volume control and mute/screen lock key, which you can now toggle between in the settings menu. There's also a single speaker grill on the bottom of the iPad 2, and a rear-facing camera up in the corner.
The problem with the Smart Cover is it only shields the front of the iPad 2, not the back. If you've owned a mobile Apple product before, then you know how scuffed up the backplate tends to get. If your primary goal is to actually protect the iPad, you'll want to look into an alternative cover (the official cover for the iPad 1 is not compatible).
