Hi Thank you for your attention. I have considered teh HP Envy in the UK at £900 with touch screen.
The trouble is a sometimes work from other peoples offices and so need something more mobile but I still need a big screen.
The UK is much more expensive for hardware I understand.
£1000 is my budget really
I suspect you are looking at the HP Envy 17-k201na. http://store.hp.com/UKStore/Merch/Product.aspx?id=ECC_BUNDLE_4900509&opt=&sel=PCNBIt has plenty of good features compared to the others in its class. One tradeoff you will have with a laptop with a screen of that size is that it will add significant weight to the laptop. The 17" screen is large but very useful if you don’t have an external display to plug it into.HP is well known for their service and support. I use HP product both home and at work and have always been happy with their products.If you want to look at a comparable product from Dell, look at their Inspiron 7000 series.: http://www.dell.com/uk/business/p/inspiron-17-7746-laptop/pd?oc=bn74604&model_id=inspiron-17-7746-laptopDell also has a good reputation in quality and support.One last manufacture that I always recommend is ASUS. They do not have a product that’s an exact match as the Dell or HP, but I have always liked their product line. Looking at their laptops with 17" screens, their tradeoff is less powerful CPU. But their prices are generally lower. They don’t sell directly, but prices can be obtained from most online retailers. I like Tiger Direct and Newegg.As I said initially, for CAD and drafting, you want a good graphics chipset. NVidia and ATI (aka AMD) make good chipsets. You will want to stay away from integrated graphics for what you need. RAM is important too. You should look for at least 8GB RAM. Beyond that it’s just a matter of aesthetics and comfort.In summary, I don’t think you can go wrong with either one of these. Both are reputable companies that have good warrantees and support.
I hope that helps. Please let me know if you have other questions.
