Sounds like the impact of streaming content over the internet has put the last nail in the coffin.
Currently I am using an HP DV7-1020US. I still feel it is plenty powerful even for its age and the media attention this laptop received is awesome. It sounds great, has a small remote that slides in and out of the laptop, an actual media center remote and my favorite feature, the integrated TV tuner (which also came with an attachable HD antenna). I love this laptop.
All said, this is an 8 - 9 year old laptop, I have replaced the power jack cable more times than I can count, then eventually the shell (which is why I had to replace the power jack cable so much) and I am still on Windows Vista (can no longer use Comodo Dragon). And thanks Microsoft for no longer supporting Media Center. Basically I have been kicking the can down the road.
I have been mulling over a new laptop for years but I have yet to find one similar to my DV7, just with upgraded components and software. My biggest requirement though, the integrated TV tuner. I love being able to hook the coaxial cable (via an attachment) directly into the laptop anywhere I go. I use this feature regularly.
Any help to steer me into a new laptop would be greatly appreciated.
