Hi, 
Using a laptop Acer 5520,

AMD Turion 64X2 1900 mhz, mobo Acer Foquene, Gpu Nvidia GeForce 8400MG, 4 GHz system memory in dual channel. 

O.S. Windows Vista Home premium

Using EBOOSTR beta v.3.0.473 build, (updated beta version 3.0.471) using the cache of a usb flash Sandisk 8 GHz. 

To date I have not had any problem. 
The system is more fluid, and the applications that I have given the priority (Excel, Autocad, Primus) work really well. 
We will update in the next few days 
Thank you 
Alessandro
