I am using the Dell studio 15 laptop last 6 months. It is absolutely fine according to my purpose. But I can suggest this is not a good one for official purpose.
Specialty it looks very nice, you can have lots of color and lots of print according to you choice. But it is glossy type surface so finger print magnetic. I will suggest to go wish 9 cell battery, I using 6 cell battery but it is not worthy. Max to max it gives back up 2-3 hrs.
When I purchased, windows vista was there with the package. I don’t know if they are providing the WIN7 now. If they provide the same it will be really a good package. Sound quality is okay type but the display quality is really superb. Moreover this is a good product by dell.
