Small and Medium Business Laptops
I would strongly suggest when it comes to Small and Medium Business Laptops,Some of the laptops like vostro 3450 laptop size 14" does not have a user replaceable hard drive that is like just over turning the laptop opening the access panel from the bottom and swap the hdd rather the whole system disassembling,currently I only see this in vostro 3550 laptop size 15.6".I feel when it comes in SMB category vostro laptop in buisness may need to extend hard drive in future which is difficult in vostro 3450,Always we are not able to buy 3550 which is 15.6" a little more heavy to carry.
This also includes when it comes to WLAN slot and WWAN card.
Most of the new laptops i have seen from the year 2011, in sony vaio ,toshiba,lenovo have the hdd slot for user replaceable in all size of laptops.
I hope this change of design would be carried out in near future in SMB laptops
