The HP Split x2 is the experience I was hoping for when I got the HP Envy x2 (that almost seems like a slick toy netbook now). At first I was worried about the size (width of the 13.3"16:9 widescreen is almost as wide as my old 15.4" 16:10 notebook which look huge next to the HP Envy x2) but my hands have no problems with the comfortable weight distribution. I actually enjoy the size more & using it more frequently as a tablet than with my HP Envy x2 though I may still be in a honeymoon phase having received it a few days ago. I did notice depending on the chair I'm sitting on does effect how much the full clamshell weight bothers my legs so there is the ergonomic issue. At home I actually prefer to sit on a 75cm Exercise Ball like this one http://www.amazon.com/gp/product/B0006U2Q60 that is supposedly-arguably healthier than more stationary chairs. Pros: Super snappy silent Performance ( 2x RAM + Haswell) is such a relief compared to the Envy x2 if you actually like to multitask on computers. Speakers are great for this form factor & a significant upgrade over HP Envy x2. I was surprised to like the 13.3" screen as much as I do (HP Envy x2 screen seems rather short now) & my trackpad is actually great. Cons: BestBuy-base screen & Wi-Fi compromises vs upgrades: The HP Envy x2 screen does indeed look ~ 2x as bright rated at 400 nit vs 200 nit for BestBuy Split x2. I'm actually considering ordering the upgraded screen option at HP that is rated at 400 nit & 1080p but I was not impressed by the screen on the HP Spectre x2 1080p at the Microsoft store (unclear if this would be the same screen as the upgrade option for the Split x2) & photos-reports of the upgraded screen from owners do not look significantly brighter so I'm not sure if it's worth all the hassle of returns-expense etc but I may want to experience it first hand. I may go back to the Microsoft store with my HP Split x2 to compare to the HP Spectre x2 1080p screen. I would also upgrade the Wireless for $20 so my 5GHz network could also be seen (without a USB adapter like this Amazon.com: Edimax EW-7811UTC AC600 Dual-Band USB Adapter, Mini Size Easy to Carry, Supports Both 11AC ( 5GHz Band ) and 11n ( 2.4GHz Band ) Wi-Fi Connectivity, Upgrades your PC / Laptop for Exceeding Streaming and Faster Download: Computers & Access that would only work docked), currently only sees my 2.4GHz Wi-Fi. My original plan was to order from HP but the $200 off $650 BestBuy deal was a tempting opportunity to give it a chance. I should mention that my sister in law was so impressed when I showed her my HP Envy x2 & HP Split x2 in BestBuy on Black Friday that she ordered one but hers does seem a bit more floppy than mine so there may be build quality variations accounting for some of the complaints. I seem to have gotten a good one with solid keyboard & trackpad but I did not install any updates yet & given some of the complaints not sure I'm in a hurry .. I'm so satisfied with the HP Split x2 ultrabook that I personally feel it is worth considering paying for the upgrades with coupon at HP Split 13t-g100 x2 PC | HPÂ® Official Store as I'd prefer brighter screen option with Dual-band Wi-Fi. I've said that 12.1-12.5" may actually be the best mobile compromise. The more you travel the more you want a light compact model like 11.6" & why some may even consider 10.1". For mostly home use so far I'm loving 13.3" & walking around in tablet mode. I should say I'm a Samsung Note 2 owner so I'm a fan of larger screens whether or not they eventually become more mainstream as the Note line has. I've read that Samsung is developing 13.3" tablets with high pixel density & even rumors of a 12.9" Apple iPads so this size may not seem as large in a few years.. Any further thoughts-comments millertime108 - others (e.g. on upgrade satisfaction & whether I should further consider it)?
