Inspiron series lappy I purchased last years when it comes in market with revised version by DELL, the performance of inspiron 3542 is best as I using since I discussed above.Friends the knowladge of computer system you also know but here I am discussing experience about dell machine, once you purchase dell pc or lappy you need not to think about services provides by dell, very nice services are available in dell, if any parts hardware of dell become not functioning service provider immediately replaced the parts and save your time, thats a good service for customer.experience of dell pc or lappy is good.
