Here's a fascinating proposal for anywone who's ever fought corporate IT for the right to use their personal laptop at work, or on the road (and who wants to carry two laptops?):
Basically treat the employee's laptop as you would treat the employees's pants: require it, pay the employee enough to buy it, and provide the infrastructure that works with it, but that's all. Give the employee the price of one laptop per two years, plus, say, the price of one major troubleshooting session per six months.
