Those pondering the purchase of an Inspiron 1520 / 1521 should probably hold off for a month or so if you can, as it looks like suitable successors will soon be available for both. The 6.6-pound 1525 and 1526 machines are the 15.4-inch replacements for the aforementioned pair and should target small businesses / low(er)-end consumers. Initial specs sheets reveal that the 1525 will be based on the Santa Rosa architecture, while the 1526 gets AMD-powered and offers up an ATI Radeon X1270 graphics set. Furthermore, the pair will feature up to 4GB of RAM, WXGA / WXGA+ / WSXGA+ panel choices, SATA hard drives, an optional Blu-ray reader (1525 only), built-in WiFi, optional WWAN and Bluetooth 2.0+EDR. You'll also find four USB 2.0 ports, a 4-pin FireWire connector, Ethernet / 56k modem, VGA out, optional HDMI, audio in / out, a 8-in-1 multicard reader, ExpressCard slot and your choice of Vista or Ubuntu Linux. Not much looks to have changed in the design department, and apparently, you'll still be able to order 'em with a custom lid color. Also, there's no definitive word on price just yet, but you can safely expect 'em to land in the same neighborhood as the units they are replacing when the duo ships to nearly every corner of the globe in mid-December.
