The BlackBerry tablet is here, and it looks astoundingly nice. Nicer than anybody expected it to be. Here’s what you need to know about the PlayBook, in 10 easy steps.

It’s amazing to see how things change in a little more than a decade. Back then, Steve Jobs preached the new iMac as the center of your digital life, the internet machine. Now, the internet machine fits in your pocket.

We’ve seen numerous announcements of tablet computers in recent weeks, as the R&D labs of the world push out their hastily assembled attempts at competing with Apple’s game-changing iPad. But are any of them up to the job?

Last week alone saw ViewSonic, Toshiba and Samsung all officially unveil new models of keyboard-less computer, with a mish-mash of operating systems and screen sizes hoping to somehow build themselves a market in the wake of Apple’s market-leading device.

The new iPod touch is almost like an iPhone 4, without the phone. Even thinner than the original, it has a Retina display, Apple A4 processor, gyroscope, and a digital camera, both on the back and for FaceTime.

Here are the main features of the new iPod touch:

• It has the iPhone’s Retina Display, a 3.5-inch IPS-based that has a razor-sharp 326ppi resolution.

The new iPod Nano hardly bigger than an oversized stamp. It does away with the click wheel (and the video camera) in favor of a multitouch screen. But how do you use it?
