Dell had my DELL Inspiron 15, 15.6 HD Touch Screen, 4th Gen i3 processor, 4G memory 500GB HD, Win 8.1, DVD, shipped the same day I ordered via UPS with tracking info! I received the unit today, December 15, 2014. I followed the instructions and within 15 minutes it was completely operable. It connected to our ATT U-Verse wireless as soon as I put in our password. I did notice the signal strength week at 3 bars instead of normal 4 and 5 I am used to. It maybe a sign of a weak internal Wi-Fi board. I am familiar with Win 7 and Win 8.1 has similar characteristics and had no problem. I had to activate McAfee and MS Office, which I purchased in my order and all installed. I have DSL internet speed as apposed to cable, but this i3 processor speed does very well surfing the internet. There were 65 Windows updates that took sometime to download and all went well. *You have to have patience and wait for things to complete loading, Next, I located the Control Panel and put that Icon on my desk top. From within the Control Panel, I located the "Disk Clean Up" and "Defragmenting" and put those Icons on my desktop for future use and reminders. I learned 20 years ago, from our company IT person, how important the Disk Clean Up and Defragmenting are to optimizing the Hard Drive in making the system run efficiently. Long story short, these 2 things may initially take an hour+ in processing time, but be patient as you will have a smoother and faster Hard Drive retrieving and processing information. In other wards, it cleans up things and I would recommend doing these 2 things periodically and will do it in a lot less time. The Touch Screen is most responsive as is the touchpad with NO issues in short time of using. In my 2 hours in between the 6 hours of being on it, without going into more details, this system is just perfect for me! Thank you DELL! Oh, I do have the first year free for Dell's Tech/phone support + 2 more years I paid.....just in case. :) Mainly knowing there will be a new Windows OS coming out soon, that is the talk. I might want to upgrade w/o any hitches??? The only thing left is to transfer everything from my non PC computer to this new DELL PC. :) I am back to MS WIN, which I like more!
