I will mainly be using it for web development using the likes of Visual Studio. Will also be using Dreamweaver, Photoshop, SQL Server, Oracle. Never got time to play games so that would not really be a requirement.
Want it to last a good few years. It doesn't have to be the smallest and lightest as it will be used at home most of the time.
Would be doing the occasional bit of video editing, this is really just for home videos.
I will say this,if you do your research with various Dell machines and then ring them...you can haggle and you may find you save a few pounds.
First thing i would say, " im interested in "x" computer but was hoping you can upgrade the hdd for the same price....(there are other deals around )...obviously you word the phone call in your own manner.
I always build the computer on Dell's site first and then ring them to save a few pounds.
Im currently writing this on a xp Dell core2duo Inspiron 6400,roughly about 3 years old. It runs PS cs2 easily and any thing else ive thrown at it. Its been an extremely reliable laptop from day one. When i got this machine,it cost me around £700,you can get a lot better machine than this for that money now.
Good luck with your purchase,keep us informed with your choice.
