When Vista launches to consumers on January 30, Microsoft will immediately make the following Extras available for Ultimate users: "Dream Scene", a utility that will allow for full-motion video desktop backgrounds; "Hold'Em"; "Hold'Em", a Vista-customized version of the Texas Hold'Em poker game; Multi-user interface language (MUIL) packs, designed to allow individuals fluent in different languages to share the same PC; BitLocker Online Secure Key Storage, where Ultimate customers will be offered a secure place to store their BitLocker encryption keys in the Online Vista Marketplace; and "Digital publications," a collection of tips and tricks, blog links and other resources for getting the most out of Ultimate.[35][36] After that, many more are expected to be announced through 2007, including a photo editing and merging tool shown at CES called "GroupShot". More detailed information regarding some of these extras can be read at the Vista Ultimate website here The Ultimate edition is aimed at high-end PC users, gamers, multimedia professionals, and PC enthusiasts. 64-bit Ultimate supports 128 GB of memory. Mainstream support for Ultimate ends on 4/10/2012; extended support ends on 4/11/2017. Another upgrade variant of Windows Vista Ultimate is the Windows Vista Ultimate Signature Edition, a limited, numbered edition of Windows Vista Ultimate that features Bill Gates' signature on the front of the packaging along with its unique number. $399.00
So I saw Vista in action, and like Scottws I was a bit impressed. So I thought I may as well go for it, considering I've got a direct x 10 compliant card and many of the games I own are getting direct x 10 patches. Company of Heroes is expected to have a DX10 patch that upps the visuals next month.
So basically Vista Business isn't for people like us, as it is stripped of all the multimedia options -- which is senseless. They all seem to have Aero which is fine, but I don't understand why Home Premium is limited to 16GB of RAM usage while the Ultimate is at 128GB. WTF!
Anyway I really want the Ultimate edition, but then I saw the price... what a heart break. $400!!!! For software! Would I rather not buy a 360?
So if I go for home premium I miss out on all the business ed. options, which is fine. But I hate being limited to 16GB RAM. Who knows how the future will shape out. So I don't care for the business edition options, then what am I missing out on?
a game performance tweaker (WinSAT): Well... I wonder how well that would work anyway?
Dream Scene", a utility that will allow for full-motion video desktop backgrounds: Sounds cool, but worth it? Nope. The rest are pretty meh. I find the following very interesting though:
Customers in Canada and the United States who purchase the Ultimate Edition (full or upgrade) before June 30, 2007 will be able to purchase additional licenses of Vista Home Premium at a cost of $49.99. These licenses will be sold online through Microsoft's web site.
That is very interesting. So could I basically sell licenses of Vista Home Premium on eBay and make some of my money back?
edit:
Had a look on eBay. Vista Ultimate upgrade and OEM are going for $250. Hmmmmmmmmm.
What's the disadvantage of going Ultimate OEM?
