Ok, so recently, our PC hard drive has started to fail on us. we keep getting "windows had a hard disk error" and whatnot. this is our 2nd pc that has failed on us, so we were wondering if we should switch to a mac mini? we mainly used it for heavy web usage (farmville, online banking, online shopping, social networking, flash gaming), iTunes, and viewing photos. so me, being the most technologically aware member of the family, brought up the idea of getting a mac mini. would it suit our needs? apparently Mac OS X is almost completely virus resistant, but i dont think it is. also will the mini be supported by Lion since it runs on a C2D? also, i think my display might not work on it. its an HP display (im not sure the output it uses) so might we be able to use it? we have a USB mouse but we will need to buy a new keyboard. we were thinking a mac mini vs http://www.bestbuy.com/site/HP+-+Factory-Refurbished+Pavilion+Slimline+Desktop+/+AMD+Sempron%26%23153%3B+Processor+/+3GB+Memory+/+320GB+Hard+Drive/1403295.p?id=1218255563471&skuId=1403295 - this. which one is better suited for our family? please help me decide!
