The 4810TZ's worth every penny. The battery life is in pure office applications loosely 7 Hours, when I watch movies and even in parallel Internet surfing is still strong 5 hours. The 1.4GHz ULV dual core CPU is also potent enough for HD movies. The hard drive is large enough with 320 GB for most users, the memory with 4GB anyway. Even Windows Vista runs very fast, from hibernation, it takes a few seconds until the device is ready for use again. In Windows 7, it may be even faster.
The device is not a desktop replacement, but then lack the power for compute-intensive applications or 3D games. Who but a compact companion needs, which even after several hours out of steam, with which one can insert also mal ne DVD (!), Which is easy, which has a reasonable keyboard and is especially quiet, which is at the right place!
