I've had this AIO for about a year and it worked fantastic with everything up to and including Windows XP.Never encountered any of the bugs I've heard reported.Phenominal quality and speed.I recently installed Windows Vista Home Premiumand NONE of it's software worked(compatiblity issue).I now have to scan through MS Paint.HP has no immediate fix for this problem otherthan a generic driver download.I highly reccommend it for many,but not ifyou're going to run any version of Windows Vista.
