Despite what detractors say, it's possible to type pretty fast on an iPad's on-screen keyboard. However, it isn't comfortable and it doesn't leave much room for anything else on the screen.
A Bluetooth keyboard solves both problems. Plus, it can act as a stand to prop up your iPad like a laptop screen and also protect it when it's in your bag.
Here, we've rounded up the best keyboard cases including folio-style models and those which simply attach to the front of your iPad using magnets.
So whether you want full-body protection or the lightest, thinnest keyboard around, you'll find it here.

Folio-style cases

Belkin Ultimate Keyboard Case

£100 inc VAT

Rating: 4/5

Compatible with iPad 2, iPad 3 and iPad 4

Belkin Ultimate Keyboard Case - keyboard

This folio-style keyboard case protects your iPad on all sides and has a clever 'SoundFlow' duct which directs audio from the speaker to the front, and it works well.

The case allows your iPad to be fixed at three different angles, and each position is steadied by magnets. Opening the case and slotting the iPad into position automatically turns the keyboard on; closing it, or flipping the keyboard back against the iPad turns it off.

Keys are kept to the bare minimum, but they're slightly bigger for it, and relatively comfortable to type on. You get the usual shortcuts to iOS functions such as search, home, volume and playback controls, but most require the use of the Fn key. That's no problem, but UK users need to adjust to the swapped positions of the @ and " keys, compared to a PC's keyboard.

Belkin claims a battery life of 160 hours, and we certainly didn't need to charge it during our testing.

Overall, the Ultimate Keyboard Case impressed us. A black version is due out soon, if you'd prefer that to the white and aluminium version. It isn't cheap, but it's one of the better iPad keyboards around.

Available in white (black coming soon).

Kensington KeyFolio Pro 2 Removable Keyboard, Case & Stand for iPad

£60 inc VAT

Rating: 4/5

Compatible with iPad 2, iPad 3 and iPad 4

Kensington KeyFolio Pro 2

The Kensington KeyFolio Pro 2 is like three products in one. It’s a smart, business-like folio case, iPad stand and removable keyboard. This means you can jettison the keyboard when you don’t need it.

The keyboard attaches magnetically to the folio case, which is neat but sturdy. Connecting the Bluetooth keyboard to the iPad was simple. Like most it charges via supplied micro USB cable.

The keys are spring loaded and provide good tactility. They are well spaced – although obviously not as much as on a full-sized keyboard. There’s a row of iOS function keys on the top row, enabling hiding and showing the on-screen keyboard, spotlight search and media playback controls.

There’s a nifty elastic strap that secures the case, and the usual cutouts for camera, volume, etc. It looks very smart, like a giant Moleskin notebook.

Once inside the case there’s no denying that the whole package is probably bulkier than a small-screen Ultrabook laptop, but it’s cheaper and carries an iPad with all those great apps you can’t travel without.

Logitech Solar Keyboard Folio

£120 inc VAT

Rating: 3/5

Compatible with iPad 2, iPad 3 and iPad 4

Logitech Solar Keyboard Folio

The Solar Folio opens like a book, with the keyboard on the left and the iPad on the right. In the middle is an aluminium tube with batteries which are charged by solar panels on the back of the case.

To use the keyboard for typing, two feet on the rubber surround hold your iPad in place just above the top row of keys. A sensor detects this, and turns the keyboard on.

The 65 keys include a dedicated number row - which the on-screen keyboard lacks - and a double-height Enter key (on the UK model). The number keys double up as shortcuts for searching, zooming and more.

You can also choose a lower viewing angle by popping the rubber feet just above the bottom row of keys, which cleverly include media playback controls.

However, it's not all good news. There are no magnets to keep the Solar Folio shut and the price is too steep.
