CONS: Large and heavy for a handheld, Private voice calling is only possible with a headset, Magnet system for joining screen and keyboard is fallible

BOTTOM LINE: Although it has a number of attractive features, we can't recommend the Advantage X7510 as a replacement for either a notebook computer or a conventional smartphone. It's also expensive if viewed as an adjunct to either device.

PROS: Big screen, usable keyboard, great for two-way video calling

CONS: Far too large to carry in the pocket, and voice calls only work with the speakerphone or a headset for privacy

CONS: Huge size, Not easy to use as a phone, Not easy to use as a camera

BOTTOM LINE: If you think of the HTC Advantage purely as smartphone, you're talling one hefty bit of kit - so big in fact that it comes in two parts. Weighing in at over 359g, the device sets some sort of record for a smartphone

BOTTOM LINE: The HTC Advantage is a tweener: it's not a UMPC like the HTC Shift and Fujitsu U810 because it doesn't run a full version of Windows. It's not a smartphone because it's too large to hold to the head, and in fact you can only use it for phone ...

BOTTOM LINE: HTC's X7510 Advantage is a new Windows Mobile 6.1 Professional smartphone that has a real focus on data. It is big and heavy, but with features like a 5" VGA display, and tri-band HSDPA data, it has loftier goals than just voice.

PROS: 5-inch screen, User-friendly keyboard, Phone module, that can be used for making calls, The options to connect to a monitor and to plug in flash memory

CONS: Sluggish OS, The mediocre visualization of large documents, The video playback cannot be used, Limited functionality in contrast to UMPC, The price and size do not justify the functionality

CONS: Price ; practicality ; camera ; graphics performance

BOTTOM LINE: The company has no plans to launch this in Asia Pacific at the moment, but as we found out, it may not be that big a deal.

PROS: Attractive and innovative design, very good VGA display, fast processor, lots of RAM, flash ROM and microdrive space. Windows Mobile 6 is powerful and has enough to offer to make this a reasonable notebook substitute if you don't need specific Windows ...

CONS: Not cheap. No option to run everything in VGA for those who have excellent eyes. Shows and holds onto fingerprints mercilessly

BOTTOM LINE: Is it a PDA, a mini-computer or a phone? It's a bit of each. While the HTC Universal (commonly sold as the i-mate JasJar and other carrier-branded names) tried to be a phone, HTC has learned that most folks don't want to hold a handheld computer to ...

BOTTOM LINE: Get all your mobile needs in one device with the HTC Advantage X7510.

BOTTOM LINE: ...but the main concept remained the same: UMPC-sized PDA that doesn't know much more than others that are a third in size.

PROS: Big, crisp display, • Clever magnetic keyboard, • Fast processor, • Accurate GPS navigation with local search

CONS: Bulky design is too big for a pocket, • Mediocre call quality, Talk/Standby Time: 4.5 hours/12.5 days, , , , , , , , Top-heavy is the best way to describe the HTC Advantage X7501. The 13.1-ounce device is almost all screen with a flat magnetic ...

BOTTOM LINE: The Windows Mobile-based Advantage offers more speed and bang for your buck than a UMPC, but is it worth three times the price of a smart phone?

CONS: Too large to be a primary mobile phone. Can make or receive calls only with headset or speakerphone. Occasional OS glitches. System performance is sluggish, even with fastest available processor. A shockingly high price.

BOTTOM LINE: Depending on how you slice it, the HTC Advantage is either a nifty miniature laptop or a huge smartphone--and that's not exactly a good place to be. It costs too much and is way too compromised to appeal to anyone aside from the niche enthusiast.

BOTTOM LINE: Poised somewhere between smartphones and UMPCs, HTC's unlocked Advantage is too compromised to excel.

BOTTOM LINE: The HTC Advantage X7510 is marketed as a €˜smart mobility' device and distinguishes itself from the WinMo pack by being neither a phone nor a laptop but offering some of the features of both.
