Acer 1662wlmi vs 2012wlmi

Anyone with any experience with the 1662wlmi ?The Acer 1662 is a P4 3 Ghz HT chip with a new acer folio design which looks attractive. Plenty has been said about the 2012 on these forums and looks to be a good choice. They are very close in price. The 1662 can be found on the web at a little lower price. I've seen as low as $1206.45. The 1662 also has dual DVD drive 512 MB memory, wireless card, Ati 9700 - 64 MB. XP pro. Problem is I cannot find a review of the 1662 anywhere on the web. Anyone seen or have experience with the 1662? Suggestions ?

I do like the idea certaintly of increased battery time but most of the time will be hooked up to AC. So, battery time is not the overriding concern. The 1662 also has 15.4" widescreen. The new folio design (acer 1662wlmi) seems appealing. For example, it has a latchless closing design that uses magnets. a metallic finish. The keyboard positioning seems more appealing on the 1662. It is further away from the screen than the 2012 that seems to butt up to the LCD. The 1662 also has what Acer calls Signal Up technology - basically better WLAN antenna performance. Anyway, I do like the layout or design of the 1662 better than the 2012. But, not being able to find anyone with user experience on the 1662, I will probably go with the 2012 because of the favorable reviews I've seen here on that machine.

Okle, Thanks for your response. As I've been checking further I find that the Acer 1662 uses the ATI 9000 IGP chipset. Some systems uses the ATI 9100 IGP. However, what I read was that the 9000 IGP chipset uses a single data rate for memory transfer and the 9100 chipset uses double data rate. I'm no computer expert so I don't know what that means unless it only refers to data transfer from/to the motherboard ? Not sure what this means. I assume that from what you mentioned that DDR memory is still supported.

Both the 1662 and 1661 use the same chipset. Link below is the article I found - mainly discussing the ATI 9100 IGP chipset.

Within the article a few comments on the 9000 chipset:

RADEON 9000 PRO IGP
For entry level value systems, today ATI has introduced the RADEON 9000 PRO IGP. While the name is a little different, the RADEON 9000 PRO IGP is built on the same fundamental architecture as the RADEON 9100 IGP, the chipset supports Intel’s 800MHz system bus as well as the older 533MHz bus just like the original RADEON 9100 IGP. ATI also uses the same integrated graphics core.

The sole change is found in the memory controller. Whereas the 9100 IGP and 9100 PRO IGP support dual-channel operation, the RADEON 9000 PRO IGP possess a single-channel interface. Because of this distinction, this chipset is intended to battle with Intel’s similarly outfitted 848P chipset, which also supports the latest Pentium 4 processors and memory technologies yet relies on a single-channel memory interface.

So, it indicates that the 9000 IGP chipset would support DDR 333 memory. The Intel chipset referenced, the Intel 848P, does support up to DDR333 SDRAM memory.

My only question is point is, (again, I'm not a techie) I'm trying to understand what the impact is on performance based on the 9000 chipset relying on a single-channel memory interface. May not mean much at all. I just don't know. Would like to know before I make a purchase decision.
