I went through a buzz to have a top of the range PC all the gadgets you could think of a few years ago, i could send you to places to get the best, or send you to others and build a custom PC to your own spec, like i used to. but I'm not going to .. simply because its not worth it at present, for any of you that read up on the latest tech in production you will be aware of blue ray dvd's the new flat screen 3d LCD TV's, what people don't realise right now with all this with screen tech the quick move to digital, then flat screens becoming super cheap to buy, the reslease of 3d TV its not leaving you room for PC life length at the moment. until things settle i won't be building a new PC until I'm sure that no real major changes will be needed for a few years, its not the money side of things that worries me on a computer, once build its worthless always has always will. what worries me that you will spend anywhere up to £2000 on a decent PC and in a years time you won't be able to do what you want given the advances currently. so heres my suggestion of a sort... Get a free laptop with one of the wireless internet dongles, thats what i did at the beginning of this year. £30 a month for 5 gig of mobile internet and a free laptop and this one i use its pretty good for free. its a hp Pavilion, it has 8n hour battery. 15.4 anamorphic wide screen (silver and gloss black finish, 250 gig hd, win 7 amd 64 processor 4 gig ram hdmi imputes and outputs 6 usb's built in card reader and webcam, full keyboard with num pad, HD resolution screen and a dvd rw with LIGHT SCRIB built in. this laptop will do everything i want from it and even play most of th games i like even some of the new ones although they would play on a better PC with a better gfx card i won't let that bother me given the laptop was basically free

when i was in town recently i spotted this laptop in one of the computer shops it cost of the shelf £899.
Although you may not be intrested in the £30 a month dongle contracts have a good think before you dismiss it.. £30 a month over 2 years =£720 total value and this is with out intrest payments for buying on credit, now the best thing i like about this method of owning a decent computer is this... every 2 years when the contract expires you have the option to renew, now with this renewal you get a brand new laptop upgrade for free this does a few things one of which is every 2 years get a new laptop with a decent set of components that will last the distance and its cheaper in your pocket to spread the cost of a new computer over 2 years with out intrest.
but until we get to a stable level of technology booms i will be using this method for a long time to come.
