With the myriad of savings possible by being online, those people who cannot afford a cheap computer, or the setup costs of getting a broadband connection for the first time are at a distinct disadvantage.
One of the jobs for Martha Lane Fox as a digital evangelist for the UK is to promote digital inclusion, and as part of that subsidised Windows PCs are available that start at £99 for those on benefits, or £149 to anyone. The Online @ Home scheme is backed by Microsoft, and also now offers discounts on a TalkTalk broadband connection (£5/month for 12 months, £50 off price of the PC and a £50 credit on the TalkTalk account to offset any activation costs).
TalkTalk is well known for almost always having one or more promotions running at a time, and people looking for the cheapest broadband would do well to ensure they shop around, e.g. you can get TalkTalk Essentials for £3.25 a month for 12 months, and a £25 Tesco voucher currently.
