All systems run very fast and stable. Have had a single crash and now only the R70 one compatibility issue with the multi-card reader, but the last 4 years was not used anyway. The laptop will boot up in half the time and run significantly faster than even under Vista. In addition, the memory with 2 GB is usually only 30% utilization.
For this offer: The update to SP1 was with my other systems annoying and time-consuming (usually 3 starts and eternal download time for the 1GB). That is why I ordered the R70 the Win7 version incl. SP1. The few euros price difference worth it in any case in order to save the update effort.
So: make the Vista from the computer and from the Window (what a pun). Very strong buy recommendation !!!
