I bought this minilaptop to browse internet and run cc for my home based business will the hardware allow this?

Stores like bestbuy will upograde anything but they'll charge you for it. Generally ram is the easiest thing to change on a computer - desktop, laptop, netbook - but that's comapred to other stuff (processor, HD, motherboard). Generally computers come with manuals that explain how to replace or add ram, and these machines are designed so that you can do that without a major tear down. You can find the right RAM by going to sites like Crucial and asking a friend or family member to actually install it for you.
