The iPad mini comes in either Wi-Fi only or Wi-Fi + Cellular options. Wi-Fi is dual-band meaning both 2.4 GHz and 5 GHz bands work fine. The mini also covers all Wi-Fi standards - a/b/g/n.
The cellular version of the iPad has two different flavors. There's a quad-band GSM/HSPA one with dual-band LTE and a CDMA version with quad-band GSM/HSPA and penta-band LTE. The cellular connectivity on the iPad mini is used for data only, so native calls are out of the question.
There's stereo Bluetooth 4.0, nano-SIM support (for the cellular units) and the lightning connector, which corresponds to USB 2.0.
Although not Retina, the iPad mini screen does a good job at web browsing on the go. The device's form factor is another key bonus here, allowing you to browse without feeling like your hands are going to fall off.
For those concerned with the lower resolution, we have to say that pages mostly look good on the 7.9" iPad mini display. Text is usually readable even at the most zoomed out point and yes, there's no comparing the mini to the iPad 3 or iPad 4, but it doesn't do much worse than the Nexus 7, for example.
The multiple tabs support and the auto fill and password managers improve the usability of the Safari browser greatly. The pop-up menus appear as small windows on the screen itself rather than occupying the display things are even more desktop-like.
You can share pages directly from the share menu in Safari. Sharing options include Mail, iMessage, Twitter and Facebook. Reading list allows you to save pages for offline reading.
The Reader mode is a great way of reading longer articles in Safari. It strips the web content of fancy fonts and ads and presents you the essential stuff that's really easy on the eye. It works alright on most pages but you won't find it available as an option on all pages. For those cases there are always other options - like Evernote Clearly and the likes.
Users that are used to browsing on a full-grown iPad will immediately appreciate the comfort of the smaller, lighter iPad mini.
The iPad mini can browse the web for 9 hours and 5 minutes, which is very impressive. It was only outdid by the Motorola RAZR MAXX and the iPhone 5.
