Like dogs, computers need attention or they will begin to run more slowly, fetch the news sluggishly, and chew up all of your favorite CDs. Tame man's best mechanical friend with today's Groupon: for $30, you get $60 worth of mobile electronics repairs for iPhones, iPods, or computers from Tech Life.

Melanie Lawson of WJXT extols Tech Life's cadre of travelling technicians, who revive flagging iPhones, iPods, and computers within the client's home or offices. After customers put out the siren call, an amicable specialist dispatches to the specified location using the company's signature light-blue Prius. Tech Life stocks key Apple parts, and technicians can resolve many common iPhone repairs and iPod issues within 15 minutes, including cracked screens, clogged charger ports, water damage, or computer-virus infestations. For the iPhone 3G, cracked glass touchscreens retire to make way for flawless replacements ($59.99), and damaged volume buttons revive under technicians’ gentle resuscitation ($59.99). An iPhone 4 can preen with a new back cover ($39.99), while the old-school classic iPod video re-competes for attention with a new front housing ($49.99). Unlike a date with the mayor to propose a ban on mayonnaise, same day appointments are often available, and a 90-day warranty covers all repairs.
