I have the recalled notebook, i filled the form, and months passed with no contact from Acer. I wrote an e-mail and no feedback. If this is the build quality, if this is the support, what will happen to my notebook when they will get it?

The parent post is misleading. In Windows 7 you can configure the taskbar to exactly look like the one in Windows XP with the titles of the programs displayed. If you are annoyed by the UAC questions you can disable entirely them like in Windows XP. The major benefit of Vista and 7 is that actually the suspend function works and does not hang the machine like Windows XP does.
