Dell’s Inspiron 4150 caters for people who are prepared to sacrifice a certain amount of portability, so long as, in return, they get a well-featured and fast notebook that can handle most applications with ease. Therefore, although this 2.85kg Mobile Pentium 4 system cannot be described as ultraportable, nor is it anything like as bulky and heavy as the 3.5kg-plus Inspiron 8200 series of genuine desktop replacement systems.
