InsideHW.com has posted a review on the Dell Studio 1535 notebook

In all probability people in Dell came to a conclusion that there is a gap between Inspiron and XPS notebook series so they decided to fill that gap with new Studio series of notebooks. This new notebook brand was presented to public in June this year and models sold under this name are intended for home users. Studio series is positioned between Inspiron and XPS series not only by its market position and price tag but also it is visually mix of those two series. By its design it leans more to XPS series (logically) because it is more attractive.
