I've installed it on my netbook this afternoon & spent a couple of hours playing around with it. So far I'm liking it! Easy (if time-consuming!) installation, the only slight problems were a conflict with Lenovo's Bluetooth software, which had to be uninstalled - no problem as I've never used it - & having to reinstall some Kaspersky components, a five-minute job.
The desk-top's going to be a different matter though - as I'll be upgrading from 32-bit Vista to 64-bit 8 it'll have to be a full install . . . I'll wait until I've got a few days to spare!
