XPS 15 - NEEDS powerhouse GPU, etc.
XPS15 could look a little better, but more importantly, the insides need some fixing.
1. GPU offers must be GDDR5 (the G being important). See notebookcheck.net and find out what Class I GPUs are missing from your options. Middle to weak Class II GPUs are useless in XPS computers. Keep those in Vostros or something else that isn't geared towards media/gamers.
2. Chiclet keyboard would be better. HP will be offering that.
3. Don't need 2 headphone jacks. Keep one, and let people use splitters if they want to. Please put a glow ring around the port.
4. Make the power port stable. Got to hand it to Mac for making it a magnet, which doesn't potentially damage the laptop port with frequent plug ins.
5. FHD always available. Don't drop the 900p like HP. Keep it in stock especially when SB is reintroduced.
6. Please read the threads on notebookreview.com for the Dell XPS 15 L501. Find the issues and correct them.
A MacBook killer will never exist unless you spend the time to make a quality competitor. XPS should be that. Not another mediocre Dell product.
Status Update: This idea has been implemented in the recently announced XPS 15. Please see Bill_B's comment for further information. Thank you for posting.
