The days of overpriced hybrids are long gone as three of this week's best聽聽can slide, twist, and rotate their screens to be used as full-on tablets. With prices starting at $385, it's a sure sign that hybrids are here to stay. If it's quad-core power you seek, we also have deals on Alienware's portable gaming rig and an Editors' Choice HP Envy at $635.

   Is It Worth It?:聽Despite its ordinary looks, the 5.6-lb. HP ENVY 15t-j100 packs an impressive array of specs starting with an Intel Core i7-4700MQ 2.4GHz Haswell quad-core processor. HP pairs the CPU with 8GB of RAM, a 1TB hard drive, and a 15.6" 1366x768 display. Though we've seen this system with dedicated graphics, today's configuration bypasses the video card, but takes advantage of coupon code "SAVE15HP", which drops its cost to an Editors' Choice price of $635.

   Is It Worth It?:聽Sony may have bid sayonara to its聽聽of PCs last month, but that doesn't stop the Duo 13 from stealing the show. Both聽听补苍诲听聽like the Duo 13's redesign, which includes a sliding screen that's easier to activate than its 11" predecessor's. A more spacious keyboard, larger 13.3" 1920x1080 touchscreen, and a bigger touchpad are also stark improvements. Under the hood of this laptop/tablet hybrid, you'll find a Core i5-4200U Haswell 1.6GHz dual-core processor, 4GB RAM, and a 128GB SSD. There's no optical drive, but you do get a stylus (for on-screen scribbling) and improved battery life, the latter of which聽聽says will get you through a full day at the office. Better yet, it's $100 under our last mention.

   Is It Worth It?:聽At 6.1 lbs., the Alienware 14 is among the heaviest 14" notebooks we've seen. However, for a gaming laptop, this system is a featherweight and "compact enough to throw in a backpack," says聽. Cut from the same cloth as the bigger Alienware 18, this 14" gaming rig features an Intel Core i7 2.4GHz Haswell quad-core processor, 8GB RAM, a 750GB 7200rpm hard drive, and an NVIDIA GeForce GT 750M 1GB video card. Not a Windows 8 fan? No sweat, this muscle machine also comes pre-loaded with Windows 7 Home Premium.
