Asus Eee Pad Transformer (£379 without keyboard, £429 with)
Our favourite iPad rival so far, the Asus Eee Pad Transformer is a 10.1in Android Honeycomb tablet that plugs into a keyboard dock, effectively turning it into a netbook. What makes this tablet special apart from this convertible design is the IPS display - which offers excellent image quality and near-perfect viewing angles - the incredible battery life, the part-metal construction and the lovely, thin design.
The issue here is that the Asus Eee Pad Transformer is in the same price bracket as the iPad 2 - some head-scratching is required if dad's dying for a tablet this Father's Day. If he wants it for some real productivity work, such as longer-form typing, editing Office docs and so on, the Asus Eee Pad Transformer is a clear winner in our book. The iPad still has better apps and games, mind.
Logitech Z906 (£298)
If dad has his own home office nook in part of the house, he'll love you for letting him fill it with the Logitech Z906. It's not cheap, but it is one of the best 5.1 sound systems designed for use with a PC, rather than a full home cinema setup.
For films, games or just good old stereo-channel music, the Logitech Z906 sounds sweeter than a jarful of honey. Like any decent surround system it comes complete with a great big subwoofer too though, so be prepared to dish out the odd strong word if you live with your dad. It can go loud, very loud!
Canon PowerShot SX230 HS (£250)
Plenty of dads think they want a hulking great big SLR, but there's little point investing in the time and money a DSLR requires if they're not going to put the work in. If that's the case, they'd be much better off with a high performance compact like the SX230 - which you're not entirely wasting by sticking to Auto mode.
The Canon PowerShot SX230 offers a 12.1-megapixel sensor, and the 14x optical zoom makes it an incredibly flexible compact. Most importantly though, it produces excellent-quality images. Unlike many entry-level DSLR cameras, the SX230 can capture 1080p video too. It's a formidable, value-packed deal.
Apple iPad 2 (£399 )
Do we even need to introduce Apple's tablet? The iPad 2 takes the original iPad design, makes it slimmer, lighter and easier to hold, whacks up the processing power and adds two cameras. It's even more desirable than the first-gen tablet, but all the good bits of that earlier model are here intact.
Those hundreds of thousands of apps are here - the iPad 2 is backwards-compatible with iPhone apps - and the superb 9.7in display is almost identical to that of the original iPad. The iPad 2 may demand a significant outlay, but it's a device that can worm its way into so many aspects of your life that it'll soon be hard to imagine living without one.
