im not knocking the quality of lenovo laptops, they are very durable, and as you said are overall a nice system. however they lack gaming style (they are business machines and look it) and they are lacking heavily in performance for your $$$, simply put for the same cost you can get a much more powerful system with 3 years of completecare and next business day onsite warranty. which really makes me say i wouldnt go lenovo (ibm).
for a business user who doesnt really want to game and needs an extremely durable laptop with okay power but doesnt want to game absolutely feel free to go lenovo or with the toshiba tecra series (i have several that i would stack right up there with ibm any day for durability). also remember that the fingerprint scanner is a neat toy feature but it cant really secure your system, its a cool thing to play with but for most people its just really a toy.
